I want you to be completely truthful on this build and see what some of the engine builders come up with for Hp numbers/ torque numbers. No need to inflate or sand bag, just honest opinions. Build 367 cubic inch engine 10:1 compression ration 340X heads 240ish .520 lift solid roller comp cam holley street dominator intake 750 proform carb 1 5/8 headers. thru 2.5 exhaust. I know this isn't an exact science, just give me guesses thanks, Mikey 1969 Dodge Dart Swinger

I know the Stock guy's with 340's make more power, but I don't know if the ARE Stock. As long as they don't pour the heads for cc's I don't trust them I built a 366 for a friend with a TIGHT budget(he is poor as he!!) I've used std J heads with 2.02 intake valves and no porting, a Edelbrock RPM, Lunati voodo cam, and a Thermoquad. Car is a original 62 4dr Dart with 8 3/4 3.23 and pushbutton 727 and Streetfighter converter. Best et 13.02@104mph Don't know the HP but we are happy as it's a NO money budget. 1970 Super Stock Challenger ex.

All depends on the machining, balancing, assembly, initial and final tuning of ALL components together. Not much cr, but I'm wondering if it's EFFECTIVE or static measured cr.

Didn't say what fuel, so I going with pump gas premium w/ octane booster to be sure. Fiddle with the cam intake and lobe center angles (degree cam), optimize ignition timing to the combo and make sure the EFFECTIVE cr IS 10 to 1, otherwise with the "advertised" cr level at 10 to 1, you are looking at 50-70hp less (maybe more!) than with EFFECTIVE cr.
