Hey all, I have a 1976 C10. Chevrolet Performance 350, Stock th350 trans and everything is stock other than the engine. Problems all started today 5/18/19. Drove truck this morning and it was fine, parked it, ran errands and came back to wash it. I noticed it wasnt idling like normal so i let it cool and came back later. I then installed a heat insulator under the carburetor (been having heat soak issues). I went to drive the truck again, and boom. Truck was idling hard (not rough but seemed as it was just idling... hard is what ill say), going into gear it would almost break your neck it shifted so hard (both drive AND reverse), I went to test drive it to see if anything else was going on, and i noticed when first starting off, the truck would have a nice hesitation to it as well. I also noticed (only happened one time today and no times before) that it did not want to shift out of whatever gear it was in (2nd I believe). I have not checked timing or anything yet, a few plugs do have oil on the threads. ANY help would be GREATLY appreciated!
