Thread: Any website that calculates HP?

I do like the idea of 1.6 rockers. One thing that captures my attention is we haven't been told what heads you have and valve size. I know you said they ran well on stock and super stock engines. Does it have 1.94 intake valves or 2.02's. Increasing lift with the smaller bore 283 (+ .060) can experience shrouding and possible material contact depending on the chamber size and valve size. If the valve will not interfere when open, consider shrouding and if it may pose a problem for your application.

Heads are as stated 'smog' heads and if I would make any changes it would be here. They are 305HO '416' heads,1.84 in.,1.5 ex.,58cc chambers,,,yeah I know,,,YUK! Not a good head for a hipo build but I can't see why they wouldn't flow enough to get a 3200 lb. vehicle in the low 15's.
They have been used on NHRA stock and SS cars with some work.

Down to 287 hp with those heads ..................

The HP is very flat from 5500 to 7500 but I don't think that will help you that much drag racing. In addition you need really good springs and lifters or you will float your valves well before 7,000 rpm ...........
