@Chad Pearsall I have 80 feet of that in the shop in Calgary that’s coming to this shop. The one side on the shop will have it down it most of the way. This is to add to that and I will I will do another mez in the front out the shop as well. I need the one in the back first. I would like to have shop complete done like next week. But it’s not that easy lol

@Marc Brulotte I didn’t want to loose the floor space on the ground. I am going to put some racking on one of the other walls and maybe some in the machine shop area
Decking a block
How far can I deck the early Cummins block? I see they make .020 thicker gasket so I imagine at least that far. My thought was decking the block to bump up compression by reducing piston to head clearance. But if I over decked the block then set my clearance by milling the piston tops then I could also reduce bowl volume and further increase compression. Even if I could get away with decking it .030 or .040 I'd be in the money I think

@Jeff Pope what compression ratio did you end up on your engine ?

@James Johnson I don’t off the top of my head. I could measure some but would be after I get moved. Must of my stuff is packed up
Time to work on trucks?
Well, we’re not quite there yet or definitely steps closer. Quick progress video.
