I'll call you when I'm ready for the AFR heads. It will likely be a few months.

You can use more duration with that 112 lobe separation and not sacrifice driveability. Something in the 235/245 range would be about right.


Also, that manifold will give you a better average horsepower, but you will sacrifice peak horsepower.

The last Engine Masters we did with a 408 we got 635 average with a dual plane, and 690 with a single plane. But, since we were racing dynos, after all......
