I have a 03 5.7 vette motor in my truck... It's a peice a cake.... I used all the truck accesories the truck computer will run the motor just fine until you get a good tune on it.

hmmm your only getting a 13.9 with a cam??? I got a 13.8 on motor with the motor stock.

Yeah, but I pulled 101mph too....

I've got a lot of issues that I'm still trying to work out with the truck. The tranny was on it's way out on the 13.9 pass!

I was also on my 20" rims/low pro tires with an open rear end, which got me a 2.4 60". I think that once the stall/80E/4.10's/Eaton get installed, I should be able to pull out some really low 13s/high 12s on the motor.

I still need to get some tuning done too.

Okay, enough ricer excuses. LOL

Hmmm your running the stock verter with that cam? I'm sure that will kill the low end.

112 or 114 LSA?

Yeah, I was going to get a converter when I did the motor, but something told me not to. I'm glad that I didn't, or I could have had a screwed up brand new converter. The tranny fluid is burned and the tranny slips between gears after 3 passes at Gainesville w/ the LS1.

The LSA is 112. It should pick up QUITE a bit with a converter, some gear, some tuning, and a non-slipping tranny.

I did the swap on my truck with 15 k on the truck. the ls1 was brand new so far my trans is doing well. I'm going to up the n20 and should see a 12 sec time slip.

nice I ws thinking abou doing the same thing, but I think money wise I will just throw ina big cam into the 5.3 and add a stall, shift kit and call it quits (unless??) you know how it goes.
