How much hp gain?
I recently replaced the iron heads on my truck and changed the cam. 350ci
My old heads were 72cc with 1.94intake and 1.60 exhaust. Cam was stock.
My new remanufactured heads have 64cc chambers with new 2.02 and 1.80 valves. The intake and exhaust ports were opened up too. My dad called it gasket matched?
New cam is summit 1102, 204-214 at .50. 421-444 lift.
My question is... is there any way to guess how much of a horse power gain it made?
Thank you
