'53 Flat Bed · 08-08-2014, 07:09 PM

This is my first post on this awesome forum. Been reading for a while.

I have a 1953 3100 that I am building with IFS and four link rear with a ford 9 inch rear end. I am putting an LS1 and 4l60E from a 2001 Camaro in it.

So the question is are there any stock LS exhaust manifold that will work without having to cut into the frame? Or are headers the only way to go and if so which ones will work? Does it have to be the block hugger or do shortys work?

This is not a high performance build. This will be a daily driver I am not concerned with horse power but prefer better gas mileage.
