It's a hydro roller cam going in a 493 stroker with stealth heads the car is a challenger with a 727 and 323 gears. It's meant to be a street thumper that runs on pumped gas. I want at least 600+ fpt and at least 550+ hp. The compression will be a little over 10.5. What do you think, I want a car that tons of low end to mid range power. Is that descriptive enough or did i miss anything?
That pretty much describes my 505.
10.38:1 compression (440 source 4.25" crank, 7.1" rods, 17cc dish pistons, older 84cc Stealth Heads.) I did some mild porting on the heads and had a multi-angle valve job done. I posted the flow numbers in another post, but I think they flowed around 285cfm at 0.600" lift.
I used the TTI 1-7/8" headers, and the small 2.5" exhaust. Intake is a RPM with Holley for now. That combination ends up being fairly tall to where I am installing a hood with a scoop on it. The Street Dominator intake would be good if you have hood clearance issues. For oiling, I used the reproduction street hemi oil pan. I enlarged the oil pickup for 1/2', but that may be over-kill. It also made finding a correct oil pickup more difficult. I think I ended up with a Mopar pickup and reshaped it a bit to fit.
I have not dynoed the engine, but the Dynomation 5 sim program puts power at 557 HP @ 4,800 RPM, and 643 ft/lbs @ 4,200 RPM. That is with the 770 cfm carb I'm using now. Just changing the carb spec to 1,000 cfm jumps power to 593 HP @ 5,800 RPM, and 665 ft/lbs @ 4,200 RPM.
