I pointed out in post #3 that it was a '69 360 HP engine. Two bolt main. I had one just like it. Many engines are cast late in the year prior to the model year. Thus, a '68 cast date for a '69 model year car. The crank and caps pictured appear to be Model A or B Ford. It's a 4 banger with not much counterbalance. Could be an old Dodge, etc. too. Or a zillion others. I still have the crank out of my '69 428 and it is available. It'll need work, but it's a factory GM 428 crank. The shipping would likely make it cost prohibitive.Sorry, I missed both the block date and the fact that there was a YH in 1969 as Jim pointed out.
Okay, I might be really loopy tonight, but neither the crank nor the caps are anywhere near being for a 428 Pontiac. They just don't make that big of hammer to beat it in place, and I swear the only thing I've been drinking is coffee. I couldn't find 428 photos so I'll make do with a photo of 3-1/4" 455 crank and caps. The above photos in post #10 look like something for a 4-bannger engine consider the narrow width of the rod journals and the small mains (and thrust is on #3 on that small crank).
