BHP vs Net HP what does the LT1 produce? - Page 2

I remember I had an on going friendly grudge with a Cobra, she finally went with a Sean Hyland 5.4 engine, slicks, towed to the tracks, running low 12s and blew the $10,000 engine. My LS1 was a daily driver, never had any issues with the drivetrain, even the 10 bolt... LOL auto with 3.23s the 10 bolt was plenty strong...

The only note I'll add is only the 340 6 pack reached 320 bhp gross, the thermo quad would be about 310 ish and the avs about 288, for the manual and 285 for auto
