Well I never had it on the dyno. I street tuned it with a wideband and with logs showing 1.16g/cyl at 6400 I was pulling around 67lb/min of air.

A little math and bench racing puts that at 570 at the crank. I was going to upgrade the cam to the other larger one and dyno it. But this other project came up

Either way... 408 and AFR225s are a proven combo. Plus it's all assembled with killer gaskets and other goodies. I also have a set of shaft mount jesels I could throw in.
