Anybody have any ideas for where i should start with main jets on a 331.
It is a holly 670 street avenger carb. It has Isky Cam, Victor Jr. Intake Manifold and AFR 185cc heads. Any thoughts would be great.
PS I'm at 5200 ft elevation.
best thig to do would be to get a LM-1 kit from innivation and see what your afr is or get a dyno tune. peeps could throw out jet numbers but it is just a guess.
