Here's a good site with all GM truck engines...

Parts are all the same but the compression does help. I believe the LQ9 rods were stronger too but I've seen 800tq out of LQ4s with arp hardware so they're all pretty solid. I'm stoked I have the LQ4 specifically due to the boost friendliness.

yep, your correct, the rods are stronger in the LQ9

The 5.3 came in 4 versions, the LM7, LM4, L33 and L59. They had roughly 285-295 HP and 325-335 ft lbs of TQ. Except for the L33, it had around 10-15 more HP.


LQ9 with 10:1 compression, would be sweet driver.
Or, look for a 2007 L76, 6.0 motor.367 HP and 375 ft. lbs of TQ.

Found in 2007 Suburban, Avalanche, Silvarado, Sierra, or Yukon XL.

That would be a great find.

well my 06 yukon 5.3 had 295 hp. My 07 yukon xl 5.3 has 320 hp.

 

[blueflamed03]

07 5.3 was LY5, 320 version.

LQ4 is 300 HP and 365 ft lbs TQ.
LQ9 is 10:1 with flattops, 347 HP and 380 ft lbs TQ.

L76 would still be the dominant one to have.

 

[Rollin Thunder]

no I think the L92 would be dominant.
