Thanks for your thought

I guess I'm going to need a different block I assume then? And then have it stroked out or not?

appreciate any more thoughts, and thank you for the 351 advice. I was kind of thinking that way myself

Also, can I still use the twisted wedge heads on the 351? i'd like to stay fuel injected- so Im assuming my green 42lb injectors will also need changing out?

I have a Treme 3550 trans too
