NicholasShetley Posted September 28, 2014 Report Share Posted September 28, 2014 I made this post to let you guys let you know what we are doing in tech school. There are about 15-20 of us in the engines class. Two of us get assigned to a project wether it is an engine one if us brought in to rebuild or wether it is a vehicle needing work. The engine we are rebuilding isn't mine but it is my partners. The engine is just a regular 4 bolt main small block chevy. Once we took the pan off we realized that there was a problem with the bottom end, the crankshaft had 10 times the minimum reccomended end play. We took the crankshaft out and checked out the thrust bearing, which controls the foreward and backward movement of the crank, and it only had worn 0.020 of an inch and there was a total of 0.060 of an inch of end play. It turns out that the other 0.040 came from the crank being worn. My partner was going to get new pistons and rods anyway so we just decided on a new 383 rotating assembly kit with new bearings, rods, pistons, rings, and a new crankshaft. In order to make a 383 cubic inch engine from a 350 you put a crankshaft from a 400 cubic inch small block chevy in it. You can get the kits with a cast crankshaft for under $900 all day long so he had no reason to go with it. That is as far as we have came in this build so far. I will try to get pictures sometime this week and I will keep you updated on this build and hopefully we will get to put if on the dyno and run it.
