so its going to be a 355 tpi, am i going to need a custom tune?? am i going to need larger injecotrs then the stock 350 ones?? what kind of hp should i be making?? really dont know but i am getting pretty excited because i am ordering most of the main engine componets tom. Also thinking about getting some edelbrock headers, anyone have any exp with those??...

you should not need larger injector as long as you tune the prom right, and yes you HAVE to get a new prom or yours redone.

and did this used to be a 305 tbi? if so, i think you will have to get a new fuel pump to supply the fuel.

that's a pretty expensive cam kit.
