Title: Speed Pro L-2291F Pistons
Post by: troublemaker427 on February 05, 2022, 11:41:46 AM

What is the approximate compression ratio everyone is seeing with a set of Speed Pro L-2291F 30 pistons at zero deck used with C1AE heads? 

Thanks

It depends on the combustion chamber volume of the C1AE heads you have.
The CC volume can vary by a significant amount.

The guess without measuring CC volume 9.8:1 to 10.8:1 (@ deck height 0.00)
