Ls3 vs procharger So I've been looking hard into putting a Procharger on my truck. It's a 2000 single cab silverado with a 5.3 with 243 heads which are cnc port, polished and milled .030 with 660 dual springs. Anyways the truck has a 4l65 transmission and I'm not thinking the transmission will handle the power. It hasn't failed me yet with 550 rwhp but I'm looking to put down 750 but here's the thing. The price I will pay for a Procharger and a transmission I can get a full ls3 swap with 10 speed transmission. If it were you guys would you go the Procharger route or do the swap??? My 5.3 runs good and pulls strong for what it is but this has me thinking.
How can you get an Ls3 with a 10 speed? Thats an LT engine that has the 10 speed in it and it requires the entire LT harness, ecu, bcm to work. Last i checked there wasnt a company out there offering a stand alone controller for the 10 speed. If that was possible id go the 6.2 10 speed vs a procharged 5.3 and 4 speed. The 5.3 would be an absolute dog down low with a procharger, i had one with an F1a and it wasnt fun.

Im aware, and i can do the labor. Bob at brutespeed told me 7 grand for the procharger kit, the truck has 42lb injectors so I may have to upgrade and it's already on e85 with an aeromotive pump so I'd have to add a second pump and I was expecting around 3-4 grand for a good transmission. Versus a donar camaro that I can everything needed out of, motor, tranny, wiring harness, ecu and whatever else is needed. I'd have to do a little research to see what else I would need from the car. But that's my options and what I'm contemplating.
