W2 408 Dyno results today !

I have less head , less cam, less spring, less header, less intake manifold.... and it pulls to 7200 and keeps pulling.

I'd like to see where the heads really start breathing and plane out. It would be something else of you knocked .075 lift and 100 lbs of spring off the combo to see how it reacts...and the intake manifold, probably is the wrong choice for that cam. I run a dual plane to about [email protected] move to single planes with a lot of 'street motors'.
