i am plaining a swap from a 305 to a 350 g.m. crate motor,both carbureted,on my emission controlled 85 z28 i need it to remain legal. do i need to replace the e.c.m. or anything else for this new engine? the new 350 crate comes with everything but the carb.,starter and fuel pump.
GMPP has the thing for you, in a complete kit! here is a link for the kit and the price. the dealer, sallee cehevy is a good place to deal with. they also have a board like this to post question's on, and tom, the owner answer's most of them.
