Quote: Don't know what it makes, we tweaked the dyno before we had any full runs. Dyno is only designed to handle 650 ft-lbs of torque and we exceeded that pretty quickly. Based on how it was pulling it will probably make 850 hp. I haven't figured out what to do yet. Either pay to upgrade the dyno or detune the motor.
Zippy - I think this block makes a bunch more power than the production block. I wanted to get a bunch of dyno pulls under my belt so I could get an answer on that question. This motor uses a lot of parts from my old 505 dyno mule so it is a fairly good comparison between the blocks.
That happened to us when we dynoed the 540. My engine builder had just bought a new Stuska(sp?) dyno and he had it on too low of a setting(he'd been just testing SB chevys on it..hehe). He said he almost wrecked the dyno..lol
