desktop dyno combo hey guys i was wondering if someone could run a desktop dyno combo real quick this motor is going into a mazda rx7 we just want to see where we're sitting
chevy 350 .030 over hyperutectic flat top pistons with valve reliefs
for a cam we have a speed pro grind
duration numbers are 288 intake 298 Exhaust 214 intake 224 exhaust at .050"
lift is .442 intake .465 exhaust
heads are vortec 906 castings unported
we've got a edelbrach performer dual plane intake
edelbrach performer 600 cfm carb
with 64 cc chambers on the vortec head we're looking at about 9.5 to 1 compression
exhuast once its in will be shorty 1 5/8" headers we'll run dual exhaust with an X pipe
thanks in advance for doing this if you could post the peak horsepower at what rpm and peak torque and what rpm in would be greatly appreciated

I guess that's a roller cam. I got 350hp @5000 rpms and 410 ft lbs of torque @ 3500.
I was curious, so I put in a Comp cam 218/224 with .495/.502 roller cam on a 112lsa and made 365hp and about 415 ft lbs of tq.
And a 224/230 with .502/.510 on a 112 lsa ran 385hp@ 5400 and 420 ft lbs @ 4000.
Remember, all of these are roller.
