Nice build thread.
Currently working in the Calgary area so maybe will get to see the build when completed!

First round of blasting got done this afternoon. Took the suspension parts down to try out a DIY sandblasting place. Best money I have spent in a while!! Endless high pressure air supply, no waiting, no clean up. Feels so good to have a few parts without rust and 50 years of grime on them. Hoping to head back there with the frame and the rear end in the morning. Supposed to snow for the next 4 days starting mid morning so I have to get this done quick.

That’s awesome man, a DIY blasting place is a great idea. Never heard of that before. Build is looking good

Ha, I've never heard of a DIY blast place. What sort of blast media is used?

Excellent job blasting. That's how the blasted parts should look, 100% white metal. Be careful doing any sheetmetal.

Yeah this place is great. The media is a medium grit sand. Took care of the rust and grime really quick but didn't seem to dig into the metal. It sits on 5 acres and has 6-7 stations big enough to bring a large trailer.

I loaded up the frame and rear end and tried to beat the snow storm this morning. Got half way to the blasting place and the storm hit. Looks like I will be waiting another week before I can get the frame blasted. Will probably tear down the LS and see what kind of shape its in. Plan is to send it off to be hot tanked and honed. Hoping I can reuse the pistons and just re-ring them. I'll be replacing all the seals and gaskets.

Not sure what I want to do for a cam. I want something that will work with the stock motor for now and L92 heads in the future.
