The 92z I just got has a 350 bored over to 357 - I think that's a negligible difference, but I'm not exactly an expert, so I was wondering if there are any things I need to change to make it run optimally, like fuel pump, injectors, prom, or anything? Obviously, I know there are always things to make the thing more powerful, I'm asking what needs to be done to make it run right - they guy I bought it from suggested that the fuel pump or injectors may be inadequate, but 350 to 357 is such a small change, was wondering what you guys think.

 

No changes necessary as long as you kept it stock. Anyone can benefit from PROM changes, even on a stock motor.

Hopefully you put a better cam (or anything better than stock) in it when it was rebuilt. Otherwise, it wouldnt be worth all the trouble of a rebuild.

 

I wasn't the one who did the rebuild, it was the previous owner, and I think he probably used the same cam, he did say that he used good parts tho, like high quality pistons and such, but I doubt he got a better crank or cam.

However, I've been thinking recently about doing a cam swap myself, I'm open to any recommendations for my setup. Thanks!
