Pwmax

At that weight, with those cubes, I would use the 2nd one myself. It will really like the duration. The lobe sep is a hair tight, but will work fine. That 1st cam is to small for even running naturaly aspirated if you want to make max power. It gets even worse on the bottle.

I am doing a pump gas 565 that will run a 300 plate, its getting an Erson, 280-292 at .050, with .807-.765. on a 112. This is a comprimise, as its a street car, lol.
