I’m the one that recommended that cam, you rember?It's still in the truck. It's a really good camshaft for what I have now. The Intake valve closes at 36* ABDC which gives my setup a shitload of dynamic compression which is great for bottom end torque. The recommended static compression for the chopper is 10.5:1 and below. The LQ9 with the 317's 72cc chambers is 10.1:1 so everything plays together nicely. The new heads have 62cc chambers giving me a 11.4:1 static CR so the dynamic CR will be way to high for the new setup. Didn't want to have to pull a lot of time out to address KR and detonation issues.
The cam motion little chopper is a great little camshaft with less than six months of use. I'll probably list it for sale with a attractive price after it's pulled.
I’m running the same came in H.O.5.3. Just curious to seeyour inputs on it.
