Well the 277 i made to the wheels was about 4 yrs ago, and was on motor on Howards dyno. Ive done a decent ammount since then to the motor alone. So with a conservative guess i should be making about 375hp on motor. Add a 125+ shot on top of that and you end up with those #'s. We’ll know for sure if i get around to getting it tuned this year!
P.S-This is all crank hp…NOT whp
