The short block is completely disassembled and at the machine shop. I am glad that I decided to break down this relatively low mileage engine! Every bearing that we pulled looked like hell and any more use without an overhaul would have ended in disaster! Luckly the machine shop I am using specializes in race engines and I have a very talented machinist working with me on this build.

And those are just the crank journal bearings! I tossed the connecting rod bearings before I had a chance to take a picture. But don't worry this engine will be reborn and be the beast it was supposed to be!

Believe it or not there was no scoring on the crank or connecting rods. Today we will be checking everything to find out if the crank needs to be turned and doing some head work.


Made some progress on the machine work today. We broke down the head and reground the valves and Mic'd the crankshaft and the cylinder bores. Looks like I will be getting the crank turned and the pistons will be getting replaced with a set of slightly bigger pistons but still the b34 piston style to keep the low compression ratio. Tomorrow the head will be getting a valve job and the ports will be smoothed out to help get the air in and exhaust out! Then it will be reassembled and bagged until it is called to duty!
