Callies Performance

Hey Guys, I just wanted to give you all a heads up. Those of you looking for moderate horsepower and torque gains, we now have full rotating assemblies for truck applications. These kits fit the 5.3/6.2 and L92/LS3 Chevrolet! During testing this engine kit yielded a 79.75 horsepower and 73.74 torque gain! Let me know what you all think! Have a great weekend! -Adam @ Callies

Can you be more specific on what parts were changed to get these numbers.

How did you get gains from just changing the rotating assembly? Less weight? More compression?

Thanks, but you see that he edited his post after I asked the question for a second time?

Yes, that cam is quite small, definitely not a stock grind though. I Like the looks of it!
