S10 V8 swap crossmember notching

sorry YouTube I wanted to bring us a point I've seen a lot of mistakes made on guys cutting cross members doing these v8 swaps mainly LS swaps if you're doing a big-block slop or you've got a notch your cross member for an aftermarket paint on a small-block or what have you these guys go in and they're measuring Center lines using basically going off that hole is what I'm guessing but most of them I've seen and they're cutting it evenly to each side they set their engine in and you got to get over here from hell and it still touches on this side here's why a v8 in a car sets or v6 they set to the passenger's side that is done to give you the additional students clearance they needed for this steering on the driver's side if you stand back and you look at this in the way that this is lined up you look at where that motor mount pads at and will that motor mount pads that it's not hard to see that this one is set further over the entire thing is set to the over to the passenger side it's not hard to see if you look under a car you'll see that it's set to that side if you come out here and say you put a straight edge up the frame over here and up the frame over here and you get them straight and you measure the centerline of your air cleaners stud to each one of those you'll notice that the engines setting closer to the passenger side again to clear the searing had to have move room for the stirring to come through without hitting the exhaust getting too close to the exhaust and so forth that's nine inches I cut out of mine and that's the fit that big-ass milodon pan eight port pan on my big-block is this cut four inches to the driver's side and five inches to the passenger side and when I set the engine in there there's about three-eighths of an inch of clearance to 5/16 somewhere in there on either side of the pan that's perfectly even I wish I made video when the engine was sitting in there if you run a stock panel a big block you don't have to cut it out like that you just might have to cut in about an inch and leave the bottom in there I think I showed one of my old videos were that's the way it was but I had to notch this out now because that pan back of the sump to the front of the sump is 10 inches where the old one was only about eight and a half and had a slope where this one goes straight down that pans also nine and a half inches deep it is an 8 quart milodon pan another thing you can use for a reference point as when you go to not you can use your bolt holes and that's what I did now this is if you have an engine in it and you go to change pans for some reason you can count your bolt holes on your old pan and see where it hits while the engine sitting in there and when you go to new pans you can count bolts and see what's at that sump is just actually right about here on the fifth bolt hole or this one is just behind the sixth bolt hole which is about an inch and 3/8 difference is what it measured out as but I went ahead and cut mine out to inches because I've got to be able to get my drain plug which extends out another half inch but again measure three times four times cut once again the engine sets in here offset to the passenger side do not then now you can use this for a centerline that's fine that's what I did that big hole right there but again it's four inches to here and five to here I believe uh let's see where is my rape measure and we will measure and see here here we go okay as you can see come over here right there centerline that's four inches going that way centerline to this side is 5 inches just like I thought I did my memory did not flip me on that one although I have slipped since I've done that but as you can see it's offset and everybody has seen my videos knows this had a big block in it there was no pan fitment issues there was no problem at all drove the truck run the truck beat out of the truck there is the engine sitting there it's going in that one I gave it to my son for all his help but again off set to the passenger side mine is an inch it come out perfect and if you're doing a small block you should unless using aftermarket pan with you know seven eight nine court or whatever the square some you shouldn't even have to cut this out with a stop five or four port pan I've never cut one out it's close but it don't hit especially if you put your motor mounts in the top position another thing don't if you're going to do anything with any horsepower and you use a two-point frame mount do not use a stock mount or this kind of happens see how that plates all bent right there motor mounts rolled around in there yeah that's only about maybe fifty miles drive time if that just trash that mount twisted it contorted it yep that's on the left side pork side where it talks up and you can see is it started shoving the mount out so yeah don't use those either use a neoprene mount polyurethane mount or a solid mount if you want to put up with the harmonics coming through your chassis that's fine I don't like it but again off set cut out for oil pan I'm not trying to sound like an ass but it's better that you know and do it now that way you don't have a inch and a half gap on this side and you barely touches on this side or barely clears and in it like me if I did that that would bother me I'd be losing sleep I'd be out here trying to fill that back in with something because I knew it was right but we test fit the engine we set it down in there we serve where the pain was setting we Center lined it with plumb lines to the motor mounts and then we seen and already knew is set to the side but didn't give us the measurements we needed to do the for and the fire but there you go if you start out with a four and five you're not going to go wrong you can trim it from there and another thing when you cut that out you need to put either brake bolts up between the motor mounts weld something between the frame I've got a piece of two by three but 3/16 tube up here for the added crossmember for added bracing one because of the power of the motor is going to make two is when you cut this out you need something to hold it together because it's going to flex this stuff is not quite three sixteenths this metal if you cut too much out of here it's gonna try to fold a little bit okay it's not going to take much to kink this because there's nothing really there if you think about it there's not much there that I want to brace it plate it they it all up and put a trust under the bottom of it but again offset your cut to passenger-side
