Cylinder head flow - What is crucial in a stocker?
I realize that most stock eliminator engines don’t have what we would call “high” amounts of valve lift. But my question is, considering the amount of dwell at maximum lifts due to our day long durations, where is improving the flow and velocity more crucial? Is it low lift, .100-.300 or what we’ll call higher lift of .350 and up? Typical engines we would not consider maximum max lift flow numbers for much more than bragging rights, and would consider the low and mid lift to be more important as the valve passes through that area twice, which yes it still does, albeit extremely fast. Obviously improving it everywhere is the best case, but often what improves low lift can hurt the high lift and vice versa. So what is the more critical area of improvement in these situations?

I predict the sound of crickets more than replies ... hopefully I will be wrong

Re: Cylinder head flow - What is crucial in a stocker?
Has anybody ever graphed their head flow against their cam?

Yes, it is! And it will vary from combo to combo.

Re: Cylinder head flow - What is crucial in a stocker?
I don't know if this is what you are looking for.
These are my basic rules: .100" lift, don't waste your time making this flow. You want the most flow at the fastest piston speed areas from 1/3 through 2/3 of the stroke. I don't monitor this page much, so any questions, please message me on my FB page. Thanks Chris Hardy RET |
