Re: new here
Welcome to the board...
If I've not talked to you before on
www.fullthrottlev6.com then you may want to look over there on the 4.3L section on the Marine Intake Manifold conversion.
I can also send you other info/pic's of how to do the swap.
Have a guy in Tx. I helped with a 2wd S-10 his is up and running.
Down pipe being the main fitment issue. Everything else was bolt on.
Again.. welcome
