I am running an asphalt modified series right now and we have to run 500 Holleys. I'm running a flat top 355 and at sea level I run 73 jets with a 5.5 power valve and the other carb that uses a power valve block off uses 80 jets. I assume that each carb may be slightly different so just read your plugs and give it the jet that your motor wants. Just use everyone elses opinion as a starting point.
