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?

 

we took a 5.3, Added the Compstar LSc Crankshaft, I Beam Rod, a Mahle dish piston, and rings.
3.900 BORE
4.000 STROKE
6.125 ROD
12CC ON THE PISTON DISH
65CC HEAD
FINAL COMPRESSION WAS 9.92 TO 1

max hp was @ 5500 rpm
max tq was @ 4300 rpm

 

Stock heads and cam?

 

And to add to that, WHAT stock heads (243/799?) and cam (Std./L33/LY5?) What year 5.3?

 

LS2 heads, right out of the box! And I am sorry, we did use a Bullet Cam
here is the info for the cam.


@ .006 intake 266 exhaust 271
@ .050 intake 210 exhaust 215
@ .200 intake 125 exhaust 129

Lobe Separation 115
Intake lobe center line 110
Lobe lift Intake .3125 Exhaust .3125

 

And what camshaft? Also, were you using a stock truck intake, if so what year?

 

@ .006 intake 266 exhaust 271
@ .050 intake 210 exhaust 215
@ .200 intake 125 exhaust 129

Lobe Separation 115
Intake lobe center line 110
Lobe lift Intake .3125 Exhaust .3125

thats a little cam too

 

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!
