Yes, 5.3 is a ls based motor. Is it worth modifying? That all depends on what type of power you want and what you will be putting the motor in. Ive seen S-10's with 5.3's in them running high 13's. The one thing i dont like about the 5.3 though is how it has dished pistons only thing dished pistons are good for is f/i.

well I am picking up a 77 corvette today more than likely and wanted to do a swap how easily could i get say 450hp out of a 5.3? also do the same rules of modification that the 5.7's like do they apply to the 5.3?
