It will be another large gain to put a good intake on it. You might hit 350hp with this thing if you keep changing things lol
Oh yeah, we "might" get 350 HP..............or beyond........maybe......
Here is the power output with the intake. We used an old Mopar M1 single plane off the storage room shelf. It is box stock 'cept for some clear coat somebody sprayed on it.
Dear me boys and girls, I know the Edelbrock RPM Performer would be a better manifold for this test, but I don't have one unless I take it off another engine. Just be thankful you get to see how the engine responds to the single plane M1.

We got a little valve float on the previous run so we backed off on the upper RPM a bit until we could be sure we were able to safely run it higher. The power was dropping of anyway so why worry the engine more than neccessary.
Next we change to the Mopar Performance 509. Wadayathink? Can we get 350 or more with less than 8:1 and the 509?
