Any readers here care to guess on the dyno HP ?

Don't be shy... No offense taken, I'll bet. ;-)

The cam is the obvious cork. The blueprinted 350 396 made 405 HP @ 5600 RPM with I think 408 cubic inches, so it would make sense it would be around 1 HP per inch, is what I was looking for. A better question is: how much average power over a certain RPM range does it take to run 11.00 @ 3500 pounds, anyone.............

Took something I had made a few changes and did a rough simulation.


DA = 0


60 Foot ET = 1.5076
330 Foot ET = 4.4113
1/8 Mile ET = 6.9378
1/8 Mile MPH = 96.7141
1000 Foot ET = 9.1421
1/4 Mile ET = 11.0173
1/4 Mile MPH = 120.2224

My guess is 500hp based on the very high quality of the build.

The first test is some what typical, and the second test was my best. From what I can see from the average power, that should get me there, 4200-6100 RPM (11.00) should be easy.

HP... I'm just wondering if you made any pulls starting at a lower RPM ? It would be interesting to see what the TORQUE numbers would be from say 2500-3500rpm. Very Good results from this project. MB
