Thanks Stewart, I think the discussion by Bill is interesting one. Probably explains why one Dyno rates a motor concervatively and another seems higher for their motors. We used steady state before back to back so always had an idea going in if we gained.

Guys it will always be a Major calculation to take all the "factors " which can affect the deal into account. I do know this the bottom line of construction of a competitive S or SS car cannot be building a favorite motor or favorite body style. You have to research the aerodynamice, the HP rating as compared to others in class etc. I like different as much as other guys at a car show, at a cruise in but if you want to WIN in drag racing you have to be careful and plan ahead and use what is SHOWN to be a winner..Dont depend on bogus as that can go away quickly and then you have a Dog on your hands.
Look at AH. No risk takers there it is ALL the same stuff, you run one quick or slow its the same pieces.

AHFS. Weak by design. Needs more tuning using Air density at the time of runs. Needs to be tighter and without a reason to run fast more places it will always be weak. Bad if not documented to be legal at the time.
