Re: Building my 283
Ok, made a bit of progress lately. Installed crank, rods and pistons few days ago. Just a few things that stood out. 1. My machine shop did a great job on the bore and hone. When I was gapping the rings i checked all the bores and all were very consistent. 2. Top rings were in spec and consistent and bottom oil rings were too but the 2 nd or middle rings were not. All were way too tight, like would have bound up tight, and had to be filed. Lesson here don't take for granted something is good out of the box.
Installed the crank gear, cam, cam gear and timing chain. All with no issues. Lastly I installed the oil pump. Had to stop with assembly there because I need to paint parts. Oil pan, timing cover, valve covers ect. I had the machine shop clean those parts up so prep will be minimal. Weather for the next few days will be awsome so that's the plan.
Since I had to wait for weather to paint, I moved my attention to the heads. I checked intake port openings with the gasket for ****s and giggles and decided right then to at least gasket match the ports. I'll post a few pics later. Machine shop assembled the heads so I disassembled them, marked the ports and got to work. Before any silly comments... I know that these power pack heads are less than ideal to start with, and matching the ports is probably an exercise with little gain but there was just too much material there to put it together like that. I'm only opening up the faces of the ports to match the gaskets and blending in an inch or so to make a smooth transition. Like I said I'll post some before and after pics later.
