True horsepower?

i guess i wasn't too clear.
for the three numbers would 350 on the dyno, 310 with accessories and 250 at the rear wheels
seem reasonable?
So then this is chassis Dyno versus engine dynos correct? whether you're chassis Dyno is the race track or an actual chassis Dyno that would read what you're asking with the wheels on the ground what it's getting back there as compared to what a motor on a stand would do by itself? So at this point I'll ask everybody's question here, who's Dino? Who's chassis Dyno? who's engine dyno? LOL:lol::popcorn::popcorn::popcorn:
