I would recommend neither. Get a quad and have a good carb. Holley's are for racing and have poor streetability. Also, if one ever backfires, the power valve will need to be replaced, every time. I've had my fill of Holley and won't ever run one again,

A good rebuildable quad is darn near impossible to find any more - Otherwise, I might run them as well.
And Scott, Holley has that old problem fixed for quite some time now. I run a couple of them and have good luck. darn old guys....
