what is the highest h.p. pump gas ls1 ????
this was 92 octane only no additives etc. 346 CI 
guy from lingenfelter has claimed a car there has done 800rwhp on pump gas, did not mention if anything else was sprayed additionally.
I think Cartek and MTI holds the record for the highest dyno'ing NA Hydr Cammed cars. Both over 550rwhp. Cartek with a 441ci I think and MTI with a 427ci I think. Now if I had the ***** I could ask Futral to step things up a bit and beat both their #'s with my upcoming 408ci..

Ok.. MTI put down 556rwhp/544rwtq out of a 427ci. Cartek put down 556rwhp/532rwtq out of a 441ci. The weird part is how did that 427ci put out more torque? I would like to see both graphs..

You could buy 4 forged 346/7/8 bottom ends for the price of 1 550 RWHP N/A motor.
But still, its up to you...

I was just surprised by the tq difference. Usually the automatics put out more tq. I am sure the drivetrain is soaking most of that up. No doubt Stealths car run the #'s and that video is SICK.. It's not everyday you get to drive around with that kind of power on the street and not fear losing a race to another car.
