Hey guys, i got a 03 silverado with a 5 speed 4.3 with a K&N CAI. Im still in the process of saving up money for a 5.7 350 TBI V8. I was wondering if anyone knew what the basic materials I would need to make this swap would be? any suggestions or input would be appreciated

 

well your going to need the wiring harnesses the ECU for that motor

also for the transmission you will have to make sure its the same bell housing or it will not fit and gear ratio so you dont blow anything

 

i knew about the wiring harness and im pretty sure the tranny is a nv3500. i still got some research to do though...

 

ok my new question is, will a NV3500 transmission work on a 5.7 350 tbi?

 

you just have to make sure the bell housing mounts on the engine properly and the input shaft is the right size for the flywheel
