I am in the middle of a Stroker build.. hung up on one thing... what is the ideal Compression ratio. I don't care what fuel grade i need to run. Premium Is A O K! but what compression ratio should I shoot for?

My currect setup will net me
9.7-1 Static compression ratio.
8.4-1 Dynamic compression ratio.

I just want to make sure I'll be ok, or If I should try and drop it a little to be on the safe side... any thoughts? what are you running on your stroker?

 

A lower compression ratio is going to be a lot less hard on all of your components and most likely give your stroked motor a longer life. I'd say with that in mind a dynamic CR of 8.4 is fine. Also you will be able to run regular fuel with that CR. The closer you get to a 10:1 CR you may have to buy premium fuel so you don't experience dentonation. Also you don't have to take the static CR into account since your motor will never have that CR.
