Starting with the first word, read post #27 very carefully.

ok well that still doesn't answer my question. nowhere in that post does it say which cam you used in that dyno sim. I was wondering if you used the one that i had posted(comp xr280r) or the one you posted for the dyno sim.

Jason, either you aren't seeing what I'm seeing, or you're on drugs. Here, I copied and pasted it....

I've run a bunch of BBC DynoSims and F-BIRD'88 is correct about using a solid roller. It just wakes up the motor and makes incredible power. I've found that the one to use is a cam that is actually designated for use as a puller or mud bog application. It's the 11-700-9 and seems to be in the sweet spot on a BBC anywhere between 9.0:1 and 10.0:1 with a 3000/3200 converter.
Here's the cam card....

Here's a DynoSim of this motor at 468 inches, stock 781 heads, 2.19"/1.88", large-tube headers through the mufflers, 850 carb on a RPM or Stealth intake.

RPM HP TQ
2000 173 455
2500 223 468
3000 283 500
3500 362 543
4000 440 577
4500 511 601
5000 564 592
5500 596 569
6000 603 527
6500 580 468
Peak volumetric efficiency 96.3% @5000
Peak BMEP 192.8 @4500

Can you see 11-700-9 and a link to click on????

yeah i see it but i didn't know if you had used that one in the sim or the one i posted earlier since that was the one i was looking at

[Jason7504]

but assuming that the cam you posted a link too was the one you used. could you run it with the comp xr280r cam and see what you get?

CamQuest says i should have around 570hp and 600tq
