Default Help with some connecting rods (LQ9)

I did a search and it returned so many results. My eyes are now literally blood shot.

Can someone give me the short answer? Will these work in my 2003 LQ9 (escalade motor) I will be using aftermarket pistons with the 317 heads to achieve a boost (turbo) friendly 8.0-9.0 compression.

These are the rods:


"26100927 Chevrolet LS1 6.100 I-Beam Connecting Rods

Product Overview


This is a 4340 forged I-Beam rod for the Chevy LS1 with ARP 8740 7/16" cap screw bolts.


Product Details


Pro Comp 4340 forged I-Beam rods with ARP 7/16" cap screws. The ultimate I-Beam rod that incorporates the strength and technology of the H-Beam rod. It incorporates all of the best features possible for an I-Beam rod plus some strength adders found in H-Beam designs. Single rib cap design for added strength and bearing support. Polished beams to eliminate stress risers. Special hollow dowels and huge 7/16" cap screw bolts greatly increase strength and horsepower capabilities. Profiled clearance for stroker applications. Rod length 6.100 Crank Pin 2.100 Wrist Pin .927 B.E. width .940"


If those rods will work then when I order my pistons (diamond, probably) I assume I can just get some 4.030 for ls series vortec 6.0L correct (my motor only has 45K on it and ran perfect when I pulled it out myself) pistons and use the stock block/crank.

Anyone??

Or recommend a good piston/rod combo with 317 heads, z06 cam and GT4202 garrett all in a 6.0L LQ9 motor.

Thanks.

They'll work fine, just make sure you order pistons that are designed for a stock length rod and not 6.125".

all ls rods are the same so you can use any of them. if they are not stock lenth just make sure the pistons match that rod lenth. what are you doing with the pistons and rods?

Thanks, guys.

I am going to put the rods and pistons in my lq9 motor and strap my turbo on it then stick it in my mustang.

Im going to get rid of them.

PM me if you want to work something out on them. They only have about 38K miles on them and the motor ran GREAT before the guy decided to let it get repo'd, but he sold the motor and trans/harness to me before he pushed it out on the street.

I am using the harness/pcm and sold the trans and transfer case.

Gonna use the stock block, crank and heads.

Gonna get rid of the stock pistons/rods and truck (03 escalade) intake.

I have the VIN and verified it was a LQ9 motor.

Lemme know.

Dan
