Has anyone done an upgrade to their factory original 340 without replacing the low compression factory pistons?
I am interested in finding out what kind of additional horsepower one could expect if they installed an (example) Edelbrock top end kit (Intake/Cam/Heads) and headers, or purchased heads with bigger valves and did nothing else.
Thank you.
