HP difference between flat tappet and roller lifters
You guys think there would be any horse power difference between flat tappet and roller lifters? I know you'd have to change cams, but assuming you had a cam that was the same lift and duration? I'm running a set of flat tappet hydraulic lifters in my 306 because it's a '76 block (non roller) Just wondering what you guys think. Also, what's the best set of roller rocker arms that mount on the stock heads without modification to the head?
