Try to limit the total mechanical {no vacuum advance} to 34-36.

Could have the incorrect power valve, or it could be ruptured. floats could be set wrong, when a Holley isn't working right they can be a real pain, that's why I use Edelbrock/Carter carbs on my daily drivers. Holleys will usually make a couple more HP. but it seems like people are always having to wrench on them to get 'em right.

I agree w/ hyper, if you arent familiar w/ a holley maybe have a wrenchin buddy dial it in for you, theyre nto that hard to figure out ounce someone shows you how.
