...anybody know if they will fit on a fullsize truck. I have a '91 with the 4.3, and I'm looking to put a turbo on it w/o having to do a lot of fab work.
The stock manifolds are pretty compact so I would guess they would work (atleast the manifolds) The issue that may come up is the crossover tube that goes in front of the motor just below the crank pulley. If it doesn't fit you could alway have another one fabbed.
ive got a extra set. pm me if you are interested they are moving up in price and i was planing on holding on a complete set of sy/ty setup. i have a complete extra every thing sy/ty in the engine compartment"except wiring harness" send me a pm on what you are looking to get.
