The heads are 2.08 valve W5's that peak flow 325 @ .700 and the lower lift numbers are really good too. The cam is a crane roller 276/.727 and 283/.727, net lift at the valve is .698/.717. You can see how much the pushrod angle affects the actual lift on the intake as both lobes measured the same.
I know it's just a sim and they may be generous but when they made 650 HP with that cam in a SS 340 it makes me think. Iron heads, stock size valves, and single thermoquad on that motor plus I have another 44 cubic inches so it makes me wonder. I've got a good bit of money invested in this block now, it's been bored and honed with a plate, tall filled with hardblock and a Hughes main girdle on it. I never really dreamed it would make 700 HP, which may be closer but I have to think now that it will do better than that.
I'd love to put it on a dyno but I don't know if I can swing it right now. Work is slow and my funds are drying up faster than the water in a Japanese nuclear reactor.
It will go together and make some passes so we'll see what happens.
