Ok folks.
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

Are you wanting numbers for a engine dyno or a chassis dyno? If on a chasis dyno which trans and converter combination or is it a stick shift set up?

Is the heads stock or ported? If stock I would guess 375-400 HP. 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@104mphDon't know the HP but we are happy as it's a NO money budget.

Thats pretty much where mine run,having a little less compression and I would say 11.30's-11.40's with this one.

With the exhaust on the dyno.. 385hp/410tq but it will vary on which muffs.... this is a wild guess since your leaving a LOT of info out of the equation

Stock 340X heads? 425HP, 430, (maybe 440) ft/lbs of torque. Ported: 460HP, 460-480 ft/lbs torque. 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.

Very similar to my combo. 360 with stock cast crank, Scat I beams, Flat top SRP pistons, calculated 11.5:1 comp ratio, old school "purple shaft" .509 cam, "J" heads with 2.02 valves, untouched ports, and shaved .100 to get .045 quench. 3500 stall PTC converter, 4.30 gears. Car is heavy at 3500 lbs with me in it.
Runs 11.80 in good air, high 11.90s in the heat.
