Whatcha having the machine shop do ?
A real valve job on the speedmasters, and a resurface. I found some of the cam bearing material was chipped off the side of 2 cam bearings, so I’m just getting them replaced after a hot tank.
I’m currently debating whether I should spend the money on this 383. #5 and #6 rod bearings were showing some copper. One of the mains was showing a small amount of copper in the groove. Looking at the bearing journals on the crank I can see small superficial blemishes. Crank and rod bearings were both standard.
I think this motor was either put together dirty, or got contaminated majorly after install. I’m not sure if anything was checked tolerance wise on this motor as one of the main bearings shows copper on the side of the bearing.
To do this right, I need a full rebuild. Do I put all of that money into the 383? The motor was free, and I can use everything but the pistons and rings on a 400, or get a new intake and go RB.
