Engle HEV 3945AS Camshaft

Maybe it's the way I see it or what level these engines are being built for but cam size seem to be on the lesser variable for a street performance v8 engines, most performance cams people seem to gravitate to is 215-255 give or take say average around 235, cid, 273 to 500+, heads 175 - 325+ cfm. Peak hp 4500 to 6500+ rpm, To me number one factor where that rpm peak will be for a given hp is displacement.

Do you know who Patrick Hale is? If you don’t like the math I use, look him up and tell him how wrong he is. It’s math he uses in his computer software.

You can think anything you want. But I have used this math enough times to know it is correct.

Stroke length, compression ratio and rpm at peak torque is what Patrick Hale says is how you determine you’re at .050 timing. I’ve tested it. He is correct.

Or, you can see if you can find a copy of the Don Terrell book where he published enough math to choke a nerd.
