Never did hear if this was a chasis dyno at the rear wheels or if it was an engine dyno. I hope, after seeing those numbers, they're at least rear wheel hp. In any case, something isn't right. That thing is anemic. Are the valves adjusted correctly. Is the cam degreed correctly. Is there a rag stuffed into the intake manifold. My small block 393 is making 398 ft. lb. of torque from 3250 rpm up to 4750 rpm +/-. Did you buy the cam, or did the engine builder supply it with the build. If you bought it, you'll definitly know about the lift and duration. I originally bought my motor and it wasn't supplied with the cam that was specified, but it's got a good one now. It really sounds valvetrain related to me, but heck, what do I know. An engine is really nothing more than an air pump.
