The numbers look like BS to me guys...

Not only is the peak torque hard to swallow given the displacement, overall build and list of components, but what is certainly not possible on that size engine is the RPM it claims to peak at (3900).

NO way no how would an engine of that displacement peak that early if it was capable of moving alot of air and producing big power....the two situtations are mutually exclusive of one another. My 383 was dialed in and with the advantage of higher flowing aftermarket parts and a solid roller cam mustered about 523 ft/lbs but note that peak occured at 4900-5000 RPM's which is more commonplace for a heavy breathing 383. Also note that even 523 is close to 1.4 ft/lbs per CID (1.37 to be exact) which is extremely strong for a pump gas engine. EMC winners are only in the low 1.4 range usually and they have a host of tricks to get there not associated with real street cars (basically they are pump gas extremely sophisticated race engines with ludicrous amounts of parts swapping and R&D involved in their development and they are aimed at very high specific torque values due to the limited RPM range in their testing with a peak of only 6500 RPM).

And dont try porting your "bowels" by yourself....LOL
