im rebuilding my motor with some forged goodies and i've found a good deal on some srp 9.5:1 compression pistions. However, originally i wanted to keep the 9.1 compression. Will this be much of a difference? Thanks

 

well, it will be a .4 difference, I say go with what ever is cheaper, it won't be that much of a diff.

 

I will be running 9.8:1 cr with about 7-14 psi. Just make sure that you tune it right and give it plenty of fuel. 98ctr

 

Yea 9.5 really isnt that bad, keep it intercooled and keep it tuned right. Cylinder pressure can be a huge problem if not dealth with correctly but .4 isnt a huge difference.
