BB Chev HP - Page 4

Dano · 04-14-2020, 12:16 PM

my combo for A is 3490 lbs, for B 3698 lbs. I would need enough hp for A and they are 9.8 - 9.90 ?
Am I figuring the class wrong? 402" with Alum Heads and Auto.....8.23 lbs per?

While vehicle aerodynamics can cause this number to go up or down I think a good middle ground is 710 HP. With track weather BP=29.92 VP=0 Temp=60

You're right. The A weight for you is 3490 and the B would be 3695 (they always round down to the nearest 5 lb spot).

Frank I'm sure it depends on what round your in and what race your at. Several people have done it on red lights and in qualifying. I think it's nuts but it's their car and money. BP

This is a factor from a B/SA 396 Camaro some years ago.
That one is Fast.
6.14/108.84
9.781/132.58
= 1297
Wonder of the RPM ;-)
