I got a buddy with a 93chevy 1500 truck with a six cylinder. He can get a 99 Vortec 5.7 with computer and wiring harness. Is there any problems swapping these computers out ?Any advice on this conversion? Also, what tranny should he use? 700R4, 4-L60E ??Thanks a lot !!!BTW motor and computer, harness are brand new!

 

Change the fuel pump over to a high pressure unit, use the 4L60E since the new computer is looking for it AND you don't have to jury-rig a T.V. cable that way, and re-flash the computer to a 96-97 model, because it won't run with the VATS that is used on the newer trucks. Everything else should go pretty well.

 

Pardon my ignorance, but hell have to reflash the NEW computer that came with the crate motor to a 96-97 model/ Also, what the hell is VATS?? Thanks!!

 

Anyone , Please!!!

I wasn't aware of a 99 Vortec 5.7 crate motor. Maybe you have something different. When I hear 99 5.7 Vortec, that typically describes the Central Port Injection engine that came in the C/K trucks. You may have something else. VATS is the Vehicle Anti Theft System that requires a special key to get the engine started.

 

Honestly Im not sure what he has. Ive only spoke with him on the phone. Thanks John
