Need a Good Website Calculator for ET to HP

Thanks,

I don't have the 1/4 ET or MPH, I may get it this weekend seeings how nothing is calculable from the ETs or 1/8 ET and MPH. The Calculators are telling me I have 167hp pulling 2.07 seconds at the 60 foot mark?? It is a modified nicely 408 engine.

If I put my ETs up here for the 0-30, 0-60, 60ft, 1/8th ET and MPH and the 1000ft ET, can you give me a ball park what my "REAL" hp is?
