I have a 1993 gmc sierra (C1500) that has a 5.7L chevy 350 small block in it and i am in need of the dimensions of the stock exhaust manifolds that are on the truck. In particular, i need the collector size but i would love it if I could get all of the dimensions for the diameters.
The reason that i need this is because i am shopping for new headers and i want to compare and make sure im not overkilling the diameter of the flange collectors because ive seen some that are 2.25 all the way to 3 inch collectors. If anyone can assist please do so.
