You'll need to know the compression and cam specs to run it on Desktop Dyno.

If possible
can i know your timing degree, exhaust (headers long or shorty, as well as mufflers y/n) and what heads are you running such as stock high permorfance street, or race

based on what i think you have for those, I have 405 hp @ 5500 RPM
and 412 lb ft @ 4000 rpm

I could get it closer with those specs though

Sinister · 04-10-2009, 09:27 AM

I have Dyno2003. I would need your cam lobe center angle, intake centerline, and exhaust centerline for the cam.
Edit: looks like bowtieboy93 has got you covered.

69swbman · 04-10-2009, 10:21 AM

cam lobe center angle 110

intake centerline 106

exhaust centerline didnt show it

timing degree 0.006

im running long tube headers with 40 series flowmasters

the heads are stock double humps 2.02 valves ported and polished with 600" springs and screw in studs

Sinister · 04-10-2009, 11:19 AM
