The Mighty Demon I tried first was tuned for a 408 stroker and was pig rich on the car but aside form some smoke and terrible mileage she ran good.

I'll try the pump cams and some more shot this weekend. The 650 speed demon never ran any better and wasn't as strong mid range/top end. Bottom end was all the same.

I've only ever run the 2 demons on the car which is why I might pick up a 3310 Holley just to see what it's like.
