I would think more NA power would be better for towing.

 

which year are you talking about? if its the same as your truck in your sig then they should be the same. the denalis didnt get the LQ9 till 05 iirc.

 

Denali’s with LQ4’s were rated at 325 & 330 depending on the year model, so yes they were rated higher, Yes they are still the exact same motor as what would have been found in a 2500/3500, the difference being in tuning and slightly different exhaust system. The biggest reason would be a milder configuration of tune due to the likely possibility of being loaded heavily. Of course in a lot of the applications it is sometimes a marketing ploy as well, you don’t want a lower end unit advertising the same as the top of the line model. In some cases it’s not exactly a lie, the HP/torque rating may just be read at a lower rpm. If you can think of a scenario, they have successfully tried it!

 

Fabulous, right on

 

Fabulous?! someones gay..

 

Just like the f-bodies and Corvettes.

 

The Fbodys and Corvettes actually use a different cam. Then you have the differences in the dual exhaust vs single exhaust, manifolds are less restrictive then the fbody ones. Years ago they did a test of the vette's manifolds vs a set of pacesetter headers and the vettes manifolds were within 5 hp of the pacesetters

 

That's correct depending on the year model, there were quite a few various cams used in the Gen III's, however even though the ’01-’03 Corvette/Camaro/Firebird all used cam ID 1721 for the base LS1, they were still rated differently. We still come back to tune, exhaust & rating differences.

 

Don''t you have a test to be taking??

 

All of you guys make sense.. I just thought it was odd that one would show higher hp when the latter truck is lighter and you would think it would be quicker for that simple fact.
