I'm going to guess the 480 produces more torque down at 2000 rpm....

Don
maybe so at the lower rpm.

I see guys suggesting the 430 and cam swaps.

If you swap the cam you'll have to custom tune which will add to the cost.

Secondly and more important IMO is you will lose the warranty on the engine. For some that's not a big deal. However if you have any thoughts of selling the car having the GM Performance warranty is nice to have.

My buddy is extremely happy with the 480 I put in his car almost 3 years ago. Never an issue.

I really like the 525 for the extra $1000. For me it's was perfect and I would go that way again. It drove perfect and the sound is different then the 480.

That said you can't go wrong with any of the LS3 crate motors.
