Just bought my 1986 K5 at 17 and ive absolutely loved square bodies since i saw one rolling down the road when i was about 10 years old, anyways I want to do some basic things and maybe get some help from some of yall older folks that know more about these trucks than me. First things first i believe I blew up the spider gears in the factory 10 bolt that has well over 200 thousand miles on it and the original 350 and 700R4 were replaced with a 350 and a th400 with a Np205 case i believe, Any tips or tricks i could get with rebuilding my rear end i already ordered a new diff for it auburn limited slip figure I might aswell get the rear axle built so i dont have to deal with it anymore as well i will need some tips as to tuning my carb and some electrical (none of my gauges work even with a brand new cluster) Thanks folks !, ill be posting some pictures soon she is crusty but trusty
she was a good gal i built a motor with some eagle rods and pistons and crank some junkyard vortec heads a summit k1103 cam and a Holley 670 truck avenger to top her off. i couldn't really notice a difference between the 2 engines but this motor blew my th400 to smithereens lost 2nd and 3rd.... well sometimes they come back from vacation and it slips in every gear the trans literally screeches so im swapping in a fresh th400 with a shift kit and such
