So i have this 351W that has a stroker kit to take it out to 392 + the overbore which I think takes it out to 395ish.. Anyhow I swing by the dyno shop today to see about getting a tune done. He looks at the car and tells me my carb is undersized. I have a Holley 600 and he says I need to up to an Avenger 770. Anyone agree with that??
