Rock soild, be a heck of a Foundation!
Oh, it has blind head bolt holes, too!
It would take sonic testing to know how thick the minor thrust axis are, but a four inch bore should easily be within reach. Not something you’d expect with a 1989 casting date and a 1990 production date.

would you be able to have it sonic tested? That would be interesting of course.

I’m thinking about it. I need to start a thread to see if there any decent budget sonic testers. I’ve been thinking about getting one for a while now.
Don't drop it on you.
I believe PBR posted about one a while back. Kim. @pittsburghracer

I wonder what the whole story is on these blocks. What does the rest of the block look like compared to the typical 318 of that era? Main webbing, etc.

Build a 390 out of it
Here’s the one I bought and use. I spent a night getting a little cheat sheet of info so I can get it set right quickly. I haven’t touched it in over a year till today to take a picture. I bought the smaller probe too.
Herb McCandless built one years ago made over 600 HP.
I’ll be able to tell you here in a few more weeks. I’ve got four (IIRC, I’ma borderline 318 poor as of late) regular hydraulic roller blocks I’m going to bridge mic’ measure the and strokes and TDC heights to see the actual deck height distance from crank centerline before disassembly So far, I can’t see any obvious differences from the bottom end. I also plan on doing some hardness testing to see if the industrial blocks have higher nickel and tin alloying content. I’m going to check that against a particularly thick 1975 year casting truck block and a regular 1973 casting block. If anything stands out in the webbing or otherwise as obviously different, we’ll know. I’m going to post pics of similarities and differences regardless.
Well then, it has to be true.
Yes, everything you read on the net is true, lol
I let my ex wife get away, but that was a good thing.
The temptation is all too real, but I would want to do beefier man caps and go ahead and take it out to a 4 inch or even larger bore. A lot of advantages to the larger bore size as far as getting more out of larger valves, but there’s a lot more “here and now” ring availability in performance four inch rings in stainless or hellfire rings. The last time hunting for 1/16 inch X 3.94 inch bore set of total seal top rings makes me brow ring selection much differently.
Me Too, Ole Buddy! Me Too…
Me too, me too. Paid here 973.00 a month starting in 1999 and recovered enough to retire at 53 in 2010. She’s still working at 64. Lmao.
Instead of looking for the strongest or best castings I can find lately, I’m collecting the scrap to experiment with and try things out on. I’m looking into getting into some “Backyard Foundry” activity and seeing what iron I can chop up and melt down to pour the water jackets full on the throw away last overbore sized blocks. And whatever cracked heads, too. Looking at the whole truck and tractor puller mentality of cooling it with a river of methanol poured down the gullet. But admittedly, I’m more just wanting to experiment with seeing if a production iron smog head could be turned into a tunnel port (or worse, stacks out of the top of the head, like a sprint engine) design. Cast on another port and next to the pushrod pinch and shape the center divider made from the port wall like a wing where it goes into the bowl. Of course, it would take a custom manifold (and probably a whole lot of unforeseen patience with getting the casting right) to make it happen. But I would like to find out how two ports divided by the pushrod pinch flows compared to one with the pushrod moved over.

Oh yeah, Mine Passed, but that means she can't just pop in and destroy things, or me.......Rip
