Desktop Dyno Help

1. Bump the compression up- it'll be fine with 9.5 and those heads. I'm assuming pump gas...

2. Run a wider LSA, to the tune of 110-112, with more lift. Look for something in the .550" range (with stock 1.75 rockers).

3. Spec out a HP 830 carb. DD doesn't have the ability to plug & play different booster or jet combos, but the 750 won't offer you the responsiveness of an 830/850. Hell- I've got a buddy that has an Edelbrock Qjet copy on a 402 that runs real nice.



4. Even though DD will show different peak power #s, the performer RPM does real well on street 402s.

A real good dyno tune will put the power where it needs to be.
