bye bye old school v-belt and hello serp belt on this old 400 sbc .
had a bottomed out and bound up and broken off head 3/8" bolt in the front of the block were i needed a bolt to go . took 2 nuts to get it out . 1st was good but she was still to tight . so the block and nub were heated up good 5-6 times glowing red on the bolt nub then welded on the 2nd nut and she come right out . chased the threads and all good . had to swap the serp belt t-stat housing in also to make the upper rad hose clear the alt .
then she was about ready to go in her new home .
serp belt system is from i think a 1994 s-10 blazer 4.3 tbi engine . i pulled it a few years ago for his old k30 truck and now getting around to the install . its got a almost new water pump and 100amp alt on it also . then the saved diesel 6.2 remote resivor p/s pump will be bolted on and pulley pressed in place .
also swapped the fan studs for bolts with lock washers . were going electric fan he said . and no a/c on this ride so the delete pulley kit was added and 1 idler pulley removed that was noisy anyway .
