Just an estimate from desktop dyno is 491 max horsepower, 508 max torque. In a Nova with 30x12 slicks, 2800 stall, and 3.73's drag 2000 shows you going [email protected] With 4.11 rear it shows [email protected] Don't know how acuarate these things are and I had to guess on a couple things to enter it in but it should be ballpark anyway.

cody, you should post this in the performance area, to get more responses. BTW if you have the Head flow numbers the Dyno is pretty close, and i'll run it for you on my DD2K is you have those numbers, if possible go to and go to there compression ratio thing plug in your numbers and find your compression, which will also make it more accurate.
