Stall change is fine. I have factory tires and wheels, the ratio is unknown. With stock heads I would love 300 hp. More would be great, but I think 300 is fair. I am stumped on selecting a cam. I do not mind higher rpm's though. My limitations are:no new heads, but I will do any upgrades that will help. No stroker yet. I am willing to have any machine work needed done. Pistons, cam, carb, rockers, machining are all fair game!
