Question 390 Pistons
I JUST BOUGHT A NEW SET OF FEDERAL MOGUAL 390 PISTONS OFF OF EBAY.
The part number is 381P-020. What compression can I get out of these pistons? Are there different pistons for different compression ratios or different heads? We will use Edelbrock heads. I have a few books but none tell the differents in the pistons. web sites?? Help
Thanks
Dwight
