Re: 289ci Piston Choice

With your combination of 4.030 - 2.87 stroke -.030 below the deck , and 60 cc head , you would need a +10 cc domed piston to get 10-1 Compression ration that would be good for an aluminum head. I found one in the Racetec/Autotec piston catalog , 1000416 that would work for you. The +11.2 dome would give 10.3 that would still be fine on 91 octane.
