Again when the car is done post some 1/8 r 1/4 track slips here.. Robert

So a lot of shop will ask are just give you a number that you are asking to make. I am sure with a very good tuner & meth & more fueling the YSI FOR SURE WILL PUT DOWN THE 1,K RWHP. But also it will need the 2.75 pulley & a excellent tuner.

As others have said it's all in the tune.

I think anything over 800 rwhp on stock LT1 rods is on borrowed time...especially if you actually run the car.


Compstar rods are much stronger.... I made 900 rwhp on compstar rods in a 402" LS for 2 years, 8k miles and never had a problem with them.... The Compstar crank on the other hand, is junk.


I think the compstar rods will be fine at 1000 rwhp (stick car)....
