Thread: LS1 swap into 53 Chevy

Tweet

Put the made to fit Speedway IFS cross member LS motor mounts on. They don't fit my TCI cross member perfect but a lot closer than a universal mount would be. We set the motor in and I don't think it's going to be awful, I think it will be about a 3-4 on the PITA scale. I need the motor higher than the 348 for steering and mechanical fan, ( which they strongly recommended ) and now the trans hits the shift linkage. Hopefully tomorrow I can get it all squared a way and figure out hoses and stuff. Not a bad looking motor until the coil packs go back on.

Seth, it doesn't fit your fast paced schedule, but some of the younger guys around here have been mounting the coil packs remote, behind a cover with extended wiring. Not at all necessary, but it cleans up the appearance as you said.

I did think about it some but I'll be fine with it the way it is. It does look good under the hood for the most part, but If I do stick in any local shows, it will probably have the hood closed anyway. Nothing real exciting under there anymore, I don't think I'm going to hear "Hey guys come check this out, this dude stuck a LS1 in here !! "

I think the PITA rating went up to a 7 today. Turns out the Vette C5 manifolds will fit if I don't want any steering. Even at that I think there was about 1/4 inch clearance between the frame rails. I found that Hooker makes a nice set of tucked in ones with a rear discharge, hopefully they work. The original pickup manifolds won't work at all, they go way too wide on this skinny frame, but I was told that already. I also got a bit of a height thing going on. I want to raise the motor about another 2 inches so the oil pan is not lower than the crossmember, then I also can use the mechanical fan and the truck power steering pump and bracket without cutting the inner fender. Problem is then my trans hits the B&M shifter linkage. I'll get something figured out, nothing money don't fix Any one interested in a 348 yet ?, please
