There are a lot of rumors online that GM underrated the 1996 LT4 motor so it wouldn't embarrass the new LS1 that came in 1997. Add this dyno session to the pile of evidence. Test was done at a local shop Shogun Speed in Colorado Springs, CO (6200'). Corrected for sea level, it produced ~317 RWHP (~250 RWHP at test conditions). I talk a bit about dyno testing, expectations, and how to interpret the results to the best of my ability. I've never done a dyno session before and am NOT AN EXPERT. All comments and thoughts are welcome. Cheers!
