tsp 408 build complete with pics and numbers!!! dyno was on a Mustang 1100SE dynamometer. I stated i was looking for 550rwhp and 500rwtq. i was informed that those number on the mustang would be around 470-480rwhp. after a few days of dyno tuning and work numbers were 462rwhp and 442rwtq. numbers were very close to what i was going for. the car has crazy torque and insane acceleration. meth kicks in at around 6 grand. car idles great and is very smooth. the stroker is even smoother than my stock ls1. very happy with the way the car drives and responds.
