am has plenty of ovarlap. It is about as big as I want to go for street truck with regular gearing 3.73's here. I have self full of bigger cams but all way big for street and solid rollers.

Looking at AFR heads if can get what I want in oval port and not over valved. This is not race car.Heck if race car or truck 14:1 with alcohol in jection would be breeze. 1/4 mpg not good.LOL
