368 LPE/Haibeck Dyno Results
Time for another good dyno report... Marc just finished a round of upgrades on my new-to-me '95 (replaced my wrecked '93 last year). The car was originally modified to a 368 by Lingenfelter, then breathed on by DRM but never reached its potential. Everything was pretty much sub-optimal. Last recorded dyno before sending the car off to Marc was around 420 RWHP. Pretty mediocre for a 368. Pulled 486 SAE RWHP/405 ft. lbs. torque on the dyno yesterday. That equates to 572 crank HP. Not bad for a 30+ year old design. Kudos to Marc for another outstanding piece of work!

486 SAE at the tire?
Wow. Impressive. Can beat Haibeck's stuff, that's for sure. At what RPM were peak power and torque?

Wow that is something. Did Mark just computer tune it only? Did he re time the cams?

Re: 368 LPE/Haibeck Dyno Results
When you say "cams"...do you mean stock cams which have had their timing changed or do you mean cams with more aggressive profiles.
If the latter tell us about the cam profiles.

Are you using the stock clutch with the 20lb flywheel?
