Before I run my car again at Pocono this weekend, I want to see if anyone has an idea of what is happening to my car.
The motor is a 351W, built up fairly well. Approx 375hp. The carb is a Holley 750 double pumper.
When I ran at Pocono a few weeks ago, the engine would misfire very badly under any kind of lateral g load. We raised the primary float up and it helped a good bit, but did not totally eliminate the problem. By the way, I'm talking about with a full fuel tank. I know there is a fule pick up issue, and I'll cure that eventually by changing the pump location.
But, with a full tank and the primary float up high, why would it still stumble under a hard g load? Is this common to the Holley 750?
