Yeah... I consiter this my first truck. I had a 86 silverado but it was a carter 4bbl 305 and didnt run right...i rebuilt it into a 383 all fixed up but then it was a hotrod. my 93 suburban... the Panzer I refer to it as. So far its had so many problems due to a lack of care from previous owners. I finally got the last thing to make it run perfect...the 350 tbi has so much torque, very happy with this engine. transmission.....this is my next problem and worry. 4L60E ? From what I have gathered its an electricly controlled 700R4, which evolved from the TH350 to give OD. My 4L60E is ready to die any day now... its starting to slip in 1st. Do I stay 4L60E? Should I upgrade it during rebuild?
