desktop dyno
Can someone desktop dyno my combo? I used to have the program on my computer but lost it due to a hard drive problem.
357ci
4.040 x 3.48
Heads: Pro Topline- Aluminum
200cc, 64cc, 2.02
Compression: 10.68:1 w/.125" domed pistons
Cam: comp cams Solid
274/280 236/242 .535/.545 (w/1.6 roller rockers)
110LSA (installed w/ 108LSA)
Intake: RPM AIR GAP
Carb: 750cfm Speed Demon, mech sec.
EXhaust: 1 5/8 headers with 2.5 pipes
This is going to be my new motor. I used Desktop dyno with my old motor and it said 332hp. I hope the new combo will be ~100hp more.

I hope to put Hooker 1 7/8" headers and sidepipes on the car sooner or later.
how will a bigger set of headers change the hp and torque? Will it have an effect on the the low end torque?

Head flow numbers
I haven't had them on a flow bench, but they came with a paper that said:

.100 .200 .300 .400 .500 .600 .700
70.74 146.41 203.72 249.84 260.51 268.51 276.41
Exhaust Port Test Data @28" of water
.100 .200 .300 .400 .500 .600 .700
56.90 100.99 156.94 176.85 186.34 190.13 194.87
Valve Timing At 0.015
Open Close
