Head flow and power differences question / discussion

He built a stock stroke 340 for me a few years ago. It has Edelbrock closed chamber heads, with a Holley 650 on an airgap intake. It made 400 Hp / 408 TQ.

It runs great with a tunnel ram, or six pack.

When I came across the Indy heads, I just had to have him build something a little more.

This new one should be fun. I found a new Chris Andrews 904 with custom converter, rmvb and low gear set to replace the 727.
