Okay, well I'm not really sure, I might get a chance to go to Lapeer Dragway (not the best place) this year. Also, I gotta let you know I had to repair the trans because the bearing retainer failed over last summer the little I got to drive it. It runs a lot better than in the original video, I have no reason to be skeptical, the thing really, really hauls. Guess I'll need to shoot another video sometime.
Not really sure exactly what I would expect on the strip, 275's all around, 18" wheels, and I bet the car is on the heavy side for a-bodies.
In any case, Mike has sold a lot of engines that were run on the same dyno and also run at the strip, I'm sure there's some info out there.
Since you're skeptical, please enlighten me on what the cork would be? Not too many people have lightened up rotating assembly, roller cam, beehive spring stock stroke 340s - and I'm sure we gained some flow with the valve job. Now I even have a super victor EFI manifold with port injection and a 1000cfm throttle body.
