The 440 stealth heads advertise an 80cc chamber. What are you guys getting on your stealth heads? I got 85 on my first cly. Ok, I’ve got 85,83,83,84 on one head. I guess if I’m wrong, at least I’m consistent! Last edited by fastmark; 02/22/20 12:24 PM.

The old Direct Connection "bible" says the NHRA Blueprint spec was 73.5 but of course that's not an as-produced number
