hello i wanted to have and estimate or if anyone have a desktop dyno. I have a 468bbc I will be running 850 holley dp on a rpm air gap, 781 heads with 2.19 1.88 valves bowl ported 118cc heads 10.2:1 compression. 1 3/4 header 3 in exhaust dumped with flowmaster 40. Im running solid roller 11-771-8 xr280r cam. I would like to have this run through a desktop dyno. Comps site is down i would like a round figure before install in the next 60days to know what I'm up against 550-580hp 500-600trq. would be awesome. Thanks to all.

Based on your numbers, Performance Trends Engine Analyzer 3.2 "Pro" says:

Peak torque occurs at 4.500 RPM, 573 lb. ft.

Peak HP occurs at 5.500, 550

Makes 551 lb, ft. @ 3,500

528 HP @ 5,000, 538 @ 6,000

We've found this simulator to be accurate within 10% ALWAYS, and usually around 5%. It CAN be a little optimistic.

FWIW

@ Mr. P-body that was very close to camquest6 simulator. Now I will be convinced to add a 100 shot of nos just for the extra kick and fun for support of my rolling burnout lol. But anyhow what will the horsepower and torque translate to the RWHP. thank much for the info this build will be a lot of fun can't wait to put those numbers to the ground.
