THE OTHER GUYS-400M POWER!!

welcome to another installment of the other guys it's not about the LS the coyote or even a small block or big block it's about the motors nobody wants today we're taking a look at a possibly feeble definitely forgotten potentially fast Ford I give you for your viewing pleasure the 400 m in this video I took a 400m before you start laughing I even rebuilt this thing I wanted the 400 m to be the very best that it could be and I know some of you were thinking hey that's a terrible motor it's neither a small-block and neither it's not a big-block it's on that gray area between and it never made any power and it's a terrible choice sure that's one way to look at it I'll tell you how I look at if you had a 351 Cleveland and you bored and stroked it to 400 inches with Cleveland head Flo that's a serious piece well that's exactly what a 400 m is sure it's a tall deck and it's harder to find intake manifolds for it but a 351 Cleveland head bolts right on in fact they come with a 2v head if you upgrade to a 4v head put a good candidate and find the right intake manifold it's a serious piece it's a 400 inch stroker 351 Cleveland and that's nothing but awesome and guess what for UD Stroke guys the 400 m comes in a short-stroke 351 version so you can rev it to the moon of course you can't do any of that but I did take a 400 m and subject it to a ton of different modifications we put aluminum heads in I tried a couple of different camshafts we tried different intake manifolds and I made a motor that actually made quite a bit of power especially for a 400 m we started mild ended up with wild so let's take a look when we take a look at our other guy make sure like share subscribe and ring the bell come on these things don't happen by themselves put a couple of buttons down there ringing up bill if you let stuff go tell some friends I'm gonna do a lot of other guys make sure you make some comments let me know your suggestions I want to do the 8.1 liter big-block I want to do maybe an SH o Taurus motor I'm definitely gonna do the big bang on a small-block Chevy got a lot of stuff coming so hey push those buttons okay we're gonna take a look again once again at the other guys and this time we're going all-in on 400 m and remember it's not a 400 M it is they tall deck stroker Cleveland and this one I actually did go all-in I didn't it's not something I just went got from the rec yard and started running I actually put a lot of effort into this yes on a 400m so I actually rebuilt this thing I even put flattop Pistons in it and the Pistons we use were not designed for a 400m they're actually designed for a Cleveland but since the compression height is closed between those two it actually worked out and on the factory 400 M's the piston is way down in the hole anyways and when we put ours in it was still down about 60 even though it was a flat top piston but it did raise the compression who brought it up somewhere and then in the nine to one range with a factory head so we put this thing together first with that piston upgrade it was a forged piston it had valve release which allowed us to run lots of camshaft because we wanted to put some camshaft in this thing so it allowed us to run that and make the upgrades but the first thing I did was put it basically back into stock configuration so we would put the stock camshaft back in it the stock stamp steel rockers the stock cylinder heads even the stock intake manifold with a stock to barrel carburetor now I didn't have an actual stock to barrel carburetor from the from the 400 m but we did have a two barrel Holley which could would satisfy most people so we equipped in with that combination our stock 400 m I just want to make sure I want to check and make sure and see if we ran this thing I think we did run this thing with headers yeah we ran out with inch and 7/8 hooker Super Comp headers for a Mustang chassis so with the two barrel carburetor induction systems dot cam stock heads and everything and our flat top pistons are 400 M produced 265 horsepower on this right a whopping 265 @ 4100 rpm really revving it out there and 412 foot-pounds of torque so the first thing I did we wanted to do one at least mild upgrade because we went kind of crazy with a thing so we put a why end four barrel intake manifold on and we ran a 750 Holley carburetor on so the four barrel intake pick things up quite a bit push it up to near 300 horsepower 397 horsepower push the torque peak out a little bit not didn't improve it dramatically but 421 foot-pounds of torque which was good now if you wanted to take this thing even further what I would recommend is you could probably mill the factory 2v heads even do a little porting on them you could stick a mild camshaft like an RV type camshaft in this thing and you would have a good little combination with headers and a four-barrel and a mild cam this thing probably would get up close to 350 horsepower and torque would probably be pushed up as well so that would be a good little combination for a 400 m in a full-size truck or you know ranch air or that kind of thing and it would work good we didn't go that route we went all in so let's find out what we did after establishing the baseline with our 400 m with the forged pistons and then the 4 burro lion intake manifold and carburetor we decided we were gonna go crazy with it so what we did was I installed a set of Pro Comp aluminum heads because they have a set of 4v aluminum heads and the thing I like about those heads is that the port volume on those is smaller than a benefactor e4v head so not only do they flow a ton more than a factory 4v cleveland head they also have smaller ports both of which I like now we had bryce from dr. Jays port these out and so they flowed like 325 or 330 CFM they flowed enough to support a lot of power even way more than we were making the other thing that I did was we put a solid roller cam shaft and that's not necessarily because we wanted to be a racy combination but it was that's what was available otherwise we would have had to have kind of a custom cam done but the guys from Crower supplied a street roller so it was more treatable and I'll go ahead and put the specs up here you could see what that cam was it was the mild milder of the two that we tried because we also stepped up and ran a cam from the guys at from MGP who are really good with this forward stuff so we put that camshaft in solid roller lifters obviously we had to change the push rods we put our ported aluminum heads in and the other thing that we did is because there is a limited number manifolds available for these we wanted to try some of the cleveland manifolds but in order to run the cleveland manifolds which are designed for a different deck height not the 400 m we had to have spacers and again the guys from n PG came to the rescue and made spacers that allowed us to run a standard 351 cleveland intake manifold which there are a lot of them will available for that on our 400 m so the first one we did was an RPM air gap from Edelbrock which is always a good intake manifold but here's a photo of what I had to do to make this thing fit I basically had to just destroy the manifold to make all this work but it was worth it in the end and the intake worked work well it made good power but let's take a look and see what happened when we installed the cylinder heads the camshaft and that rpm air gap intake manifold all in one shot big big changes in power the power output jumped to 489 horsepower torque was way up to 502 foot-pounds of torque that's really good power you know lots of head flow more camshaft obviously we moved peak power out farther in the rpm range all that stuff's good but I wasn't done there after I did this what I did was install a single plane intake that was actually designed for this the 400m deck height so it was actually a 400 M intake manifold and it was designed by the guys at CH I heads and if you're familiar back in the day these guys we working with John Kaase they make really good cylinder heads and they make really good intake manifold and I happen to get a hold of one of these and it was designed for this 400 M so we installed that single plane intake manifold and it was also designed for a Dominator style carburetor so we installed that single plane intake and the big carburetor traded power down low as single planes always do compared to dual planes picked up a bunch of power at the top so equipped with that intake manifold the power output of our 400 m remember we're talking about or should I say our told stroker cleveland produced 529 horsepower torque peak torque was about the same at five hundred and six foot-pounds the peak just happened later in the RPM range now let's take a look and see what happened when I installed even more camshaft our final group of testing because we read a ton of stuff on this 400m you'll remember this is our stock motor with the four-barrel on it and then we installed the Pro Comp heads and the dual plane intake on it with the Crower solid roller street cam street roller and then we installed the single plane intake after selling the dual plane so that's where we were I want to show you now is I'm going to get it rid of the single plane here's what happened when we installed the even hotter roller cam from MPI's at mpg and we'll compare both the dual plane versus the dual plane and the single plane versus a single plane because I ran both of those intakes also with this camshaft so here's what happened when we installed the mpg camshaft maybe you can see lots of lift more duration it's basically a hotter camp but those guys really know they're doing especially with these with these Cleveland's so here's the power gain from the camshaft and run with the same rpm air gap and the adapters for the intake manifold so the power output with that combination jumped up to 528 229 F 528 horsepower peak torque was up to 525 foot-pounds as you can see that camshaft even though it was quite a bit wilder than the street profile for the Crower one that we had run which I liked it basically made more power everywhere from 3,000 rpm all the way up to 6,500 rpms was a good combination and remember this 400 m originally started out it was factory rated at less than a hundred and seventy five horsepower it made peak torque at lower than 3500 rpm I mean peak horsepower at less than 3500 rpm and made peak torque at 2000 rpm so you can see how far we've come it's a it's a long way so now I want to show you what happened let's get rid of our two dual plane combinations and this is our single plane with the Crower Street roller and a single plane intake from c-h-i so here's what happened after we installed the camshaft from MGP with the single plane intake and that same Dominator carburetor again just like with the dual plane the mpg cam made more power everywhere even though it was quite a bit you know bigger and more aggressive but equipped with that camshaft our 400m produce 568 horsepower and 542 foot-pounds of torque again a 400 M or a tall Dexter over Cleveland this is a good combination and you could actually probably make this kind of power with a flat tappet cam or a hydraulic roller because we're only talking about a motor that makes peak power at 62 or 63 or 61 or yeah 6100 rpm we're not revving it very high and there's good reason for that because this still had factory rods in it they're really long and not very many people make aftermarket rods for that combination I would also like to get the piston up to 0 deck because right now it's about it was this was about 60 or 70 down in the hole which again it's not good not good for it makes him detonation prone and stuff and it's just not a good situation you want that thing to be at or near zero deck and if I had more time and we source the things out we could have done that but 568 horsepower 542 foot-pounds all from a400m and I know that there's a lot left in this combination if we would have spent more time with it and actually had a reasonable compression that was above 91 so there we go let's get to our conclusion ok guys what did you think of our other guy 400 m personally I really like it like I said before I think the 400 m gets a bad rap I mean sure it has a really tall deck and so you have to have these joy want long push rods and connecting rods and all that stuff it has and it has problems associated with it it was never very popular but again I look at it as a 400 inch tall BEC stroker cleveland motor I mean the ported aluminum heads that we put on it worked very well they flow very well so you can make a ton of power you can make way more than we made because we didn't have a lot of compression in this thing you can put lots of camshafts in you can put a big roller camshaft in it and really think about it forget about the tall deck and forget about the the negative connotation of being a 400 m if you had a 400 inch motor with cleveland heads on it and you had a lots of compression and you had you had a big roller cam you can make some serious power and guess what they'll also take boost I don't know who you're going to make special connecting rods for it but you definitely could even the stock stuff we've run boost on these things we've run centrifugal superchargers on them and they work pretty well just like everything else so the 400 m can make power you just got to put the right stuff on it and I can't believe that I've cut out that intake manifold to make it fit but sometimes you got to do what you got to do thanks for watching guys again make sure to like share subscribe ring the bell do all that stuff I'll keep testing more other guy stuff coming up
