I am planning on stroking my 89 GTA 350 to a 383 and wondering what other mods I am going to have to do to make this possible, anything helps.

Thanks

 

You'll want to think about larger injectors, larger exhaust and ECM programming. Those are the (3) things I could think of off the bat. How much power are you estimating? If it's alot and your using a manual tranny well then you know what I'm going to say there and if your using a 700r4 I'd recommend (not necessary but good piece of mind) is a tranny rebuild and shift kit.

 

The engine builder says I should be getting around 410 at the crank
