Thank you! I hesitate to mess with the 391 as it runs so well, but we might be re-locating cross-country, and driving a gutless wonder that far would make me consider a piston swap, and cam.
what about the cam gear? is there an advanced timing version?
390 heads, 360 pistons (why not 390 pistons?) edelbrock intake, headers etc.
