its just a straight forward swap form one 350 (stock) to another 350(older block) cause i have a mild 350 that came out of my brothers pick up and was wondering if i could just swap my tpi sytem to it cause i would like to keep it fuel injected i understand that i would have to put bigger injectors. but it would just bolt up right???

Only difference may be the late cast iron heads have the center 2 intake bolts at a different angle so you have to elongate those holes to fit earlier (pre 86 ) heads.
Otherwise it's a bolt up
Won't have to change the injectors ( 350 to 350 ) but may need a retune to get best out of new combo

thier aluminum heads so i should be good thier thanks for the help
