Do they make headers for the Olds 350 in squarebody trucks? Nice truck by the way.

Dang, that truck is NICE! I love me some long bed!  Dig the paint too.

You should swap a 6.5TD in there. ;D

Not that I was able to find.  I had to "massage" them in a few areas but for the most part there is room for them.

     A 455 OLDS sure would liven that truck up.....Tom

Punch it .068" over and put 425 pistons in it. You'll bump your CR up from 7.5:1 to 10.5:1 as well. Nice inexpensive way to make it go
