Was talking to my buddy and he says the 5.3 ls motors out of trucks are easy to find for cheap but i want a 450hp motor so anyone know if its easy to get that high with one of these or should i just spend more for an ls1?

Someone listed a 5.3 on here for $1200 w/60k miles it.

Agreed. Buy a 3rd gen gas tank from a TPI or TBI car, new high pressure fuel pump, and install used LS1 with an aftermarket harness and custom motor mounts. If your car has a 700R4, I'm almost positive the 4L60E is the same size and would bolt right up to your existing crossmember and driveshaft.

No drop tank, he already has the carb fuel sending unit. I'd put a inline pump just for ease. That and if the fuel pump ever dies it is a 20 min swap vs 2.5 hours. lol

FAST setup and be done with it. That way you aren't trying to match up factory wiring with older stuff. It is a PITA. With the stand alone ECU's it makes the install a breeze.
