Horsepower and Torque

[wnesbitt]

I was wondering if anyone would know the peak horsepower and torque and at what RPM each occurs at on my 1997 Silverado with the 5.7 (350)? Is there a website that would show this, along with the differences and improvements made from 1996 to 1998.

 

Thanks.

255hp @ 4600

330tq @ 2800

 

1996-1998 were all the same power-wise for the 5.7 if I'm not mistaken.

Where do you find this information?

And the weird thing is the toqure and horse power cross on the graph at 5250 rpms??

It does, its just that, that motor falls flat on its face after peak HP.

This is a good resource

Also those are FlyWheel numbers, figure about a 20-25% drivetrain loss.
