Ford's Modern Day 427 SOHC Cammer..

what's going on everybody welcome back to the channel so a few weeks ago i made a video about the 427 single overhead cam camera and its history in the in that video i made reference to the fact that it proved the way for the modular engines of today starting with the two valve three valve four valve and even the coyote but there is one engine in the family that kind of gets left out and it is the most truest form back to the 427 single overhead cam engine and that's the 6.2 liter single overhead cam engine so today we're going to dive into that engine and let you be the judge of whether or not this qualifies as a modern day version of the camera so let's get started on this video by the 2005 model year the mustang had a complete departure from the new edge body style from 99 to and the two valve engine it was replaced with this new body style called s197 and it came equipped with a three valve 4.6 liter engine little did we know as ford enthusiasts that we were going to get a glimpse of what might have become one of the greatest mustang engines of all time but it never happened so that's where the story is going from this point in 2007 muscle mustangs and fast forwards did an article on this particular car don boll's cold digger six this car was built in conjunction with roush performance and the factory ford engineers but what was really appealing about it was what was underneath the hood it was a mystery engine that no one had ever seen before and it was going to lay the base's 4 to 6.2 liter engine down the road this mystery engine was dubbed as project 777 which stands for 7 liters 7000 rpms making 700 horsepower but the actual output of this engine was closer to 800 horsepower this engine not by coincidence displaced the magic 427 cubic inches just like the camera did back in 1964. the boar stroke combination used to come up with the magic 427 cubic inch number came by using a four 125 bore with a four inch stroke and as you can see by the casting in this block it says the boss is back meaning that that ford engineers had a bigger plan for this engine down the road don boles ran this combination for a couple years running on e85 and weighing in at 33 to 3500 pounds this car was an 8 second performer naturally aspirated this v8 is our all-new 6.2 liter that's just been launched in the super duty and now is available in the f-150 it's got a big cast iron block big heads best-in-class 411 horsepower 434 pounds at 4 500 rpm the truck equipped with a 6.2 liter will pull a load of 11 300 pounds obviously it's got great performance a large bore and a shorter strobe so that really means we can fill those cylinders effectively and deliver a lot of power each time we fire those twin spark plugs the 6.2 liter engine is different from the domestic competitive engines out there it features a single overhead camshaft gives us a really stiff valve train and we have dual equal vct cam timing similar to twin independent vct it allows us to optimize the torque throughout the speed range and also optimize fuel economy at the same time as soon as you step on the gas and really demand a quick pull away it's going to be running up the rev range and it's just going to be eager to work this engine is going to appeal to somebody who wants a truck that's fully capable to tow and haul and work deliver day in day out and be durable the interesting part about this whole story is the fact that what was an eight second quarter mile engine was now being installed into f series pickup trucks and the first generation raptor this engine would never be destined to go into a mustang body from the factory which was a shame because even though that ford reduced the displacement down from 427 cubic inches to 6.2 liter which is 379 cubic inches the architecture of this engine is almost identical between the 427 camera looking at the valve arrangements in the head and looking at the y block bottom end it just shows that this thing has roots back to the original camera the end of the line for the 6.2 liter single overhead cam engine came in the form of a 7.3 liter pushrod engine from ford nicknamed the godzilla this engine is truly amazing if you want to find out more information about this engine you can go over to rev evan's youtube channel and he's done extensive work with brian wolfe and the power that they are producing with this engine is completely phenomenal but let's get back to the 6.2 if you want to use a 6.2 in a performance application there is a ton of performance potential there with the cylinder heads i've actually flow tested the 6.2 liter cylinder heads on david faisard's flow bench and completely out of the box stock they flowed 320 cfm and after a minor cleanup we were able to obtain 375 cfm even with using the stock valves so even though the engine has a ton of potential power wise there are some obstacles that you just have to overcome and that's parts availability getting some serious ground camshaft something that's meant for a race application is a pretty expensive deal to do but since we're building a 6.2 we also have a 7.3 so i don't know which one we're going to do and the reason why we decided to go the 6-2 route initially because it was before the 7.3 and that is to replace the engine in old blue the 96 mustang gt that i used to have that i sold to my good buddy and friend micah monteleone of gaston automotive services we're going to replace the 2-valve 4.6 liter engine in it that's in it now but there is some interesting similarities between the 6.2 and the godzilla and guess what it has the same bore spacing we've actually took a 7.3 liter crankshaft and laid it in the 6.2 pretty much making a factory built stroker um you can purchase the 7.3 liter crankshaft at the ford dealership and it's fairly reasonable the only difference is you have to modify the front of the crank so that you can drive the oil pump on the 6.2 because of the unique oil pump drive that the 7.3 has it's not equipped for it but nevertheless let's take a look at what i have here this is a junk head that i got from micah and the reason why we got this was so that we can actually chop it up into sections to see how thick the cast in itself is so that we know how far we can actually push our porting on the 6.2 liter heads as you can see the rocker arrangement is very reminiscent of this 427 camera but there is some things that needs to be addressed on the original camera you had an adjustment screw here that adjust the lash onto the valve tip this setup being used in production trucks uses a hydraulic glass adjuster here in the end of the rocker it's a great setup in a stock application but when you start running really large camshafts you're going to run into an issue because this thing has a swinging foot i don't know if you can see that but that foot actually moves to maintain proper geometry on the valve tip itself so whether we take and modify these rocker arms to accept a regular adjust and screw like it was found on a traditional camera i don't know or since we have a 7.3 godzilla now we may just go that route but i can tell you this you will probably see it here on the channel and until next time this is andy from unity motorsports garage i'll catch you later and yes someone needs to develop camera valve covers and a timing cover for this engine and it would look the part see ya [Music] you
