GPW Engine Block

Post by Bruce W » Sat Dec 31, 2022 2:46 pm

I got this block among some other parts and don't need it. In fact, I'll be honest; I wouldn't use it. But maybe someone can use it in a static display or in a jeep that will be driven very little. Here's what it is:
The serial number pad has been ground off and stamped with what looks to be a California ID number. The original serial number is completely gone.
Someone put a lot of money into this block and then didn't use it. It has been cleaned, bored .080" over size, decked, all 8 valve seats have been replaced, freeze plugs and gallery plugs have all been replaced, the cam bearing has been installed, all 8 valve guides have been replaced, and 14 of the head stud holes have been Heli-coiled.
And now the bad stuff.
The left lower bell housing mounting ear has been broken, right through the bolt hole. I suppose a bolt would stay in place. Maybe a piece or a washer could be welded/brazed on to help support it.
Two cracks in the deck have been pinned, and there are more "baby cracks" that maybe should have been pinned.
Whoever cut the block for the valve seats got a little carried away, and the seats are all too deep in their bores.
As was mentioned, it's been bored .080" oversize, and 14 (why not all 15, at that point? IDK) of the head stud holes have been Heli-coiled.
I don't have any other internal or external parts to go with it. No head, no manifolds, no oil pan, no crankshaft, etc, etc. I DO have the main bearing caps and bolts and they will be included.
Like I said, I wouldn't use it. My jeeps get used hard and I want them to last. I thought that this could possibly be used in a static display or in a jeep that is only driven in and out of the garage and/or at shows, by someone who REALLY wants an actual GPW block. PO evidently spent well over $1,000 on it, and I suppose it could be saved and repaired, but it's likely to take that much again or more.
I'm not sure what to price it at, but if someone does want to make it run, most of the work that has been done does have some value. So I'm going to price it at $300 and see what happens. Plus shipping, of course.
Thanks for looking, and HAPPY NEW YEAR! BW

No interest at all, eh? Well, I thought there would always be somebody who would buy anything with an “F” on it. I understand, it has a lot of problems.
Would anyone care to make an offer? I’ll accept offers through the end of January, then best offer gets it. Please make offers by PM so it won’t become an auction. Not that I expect that much action. I have two offers now; one from the scrap man, and one from a guy that will harvest the new guides out of it and then scrap it. I dont want that to happen, but I need the space more than I need this block.
Thanks for looking. BW

Yeah, I noticed that. Sign of the times, I guess.

Last day to make a ridiculous offer on this block. Somebody bring me $40 and take it home.

I use them for lawn ornaments; I can tell you that after 65years, they will settle down into the dirt about 1 inch. So after 100 years, they will be completely covered and will become artifacts for future archeologists.
Also, young guys can't/won't/don't want to learn how to rebuild engines; they all want them already running. Which is why I have 9 blocks around here....last one is an early M38. Actually the last one is a 440 block that the guy had bored to .060, with new pistons. Then he up and died.....
440 prefix block is an Americar block, for you guys under 60.

I don’t have any lawn; the county says I already have too many yard ornaments. I use two F-head blocks for balast on my spike-tooth harrow.
The guy that wants the valve guides says he will pick it up this weekend. I hope he is successful in harvesting the guides. At least something will be saved and used. Then it will be shredded and sent to China, then come back to us as soft transmission gears. Too bad. Another GPW, somewhere in the future, will have to be content with a post-war engine.

Every once and a while somebody here is looking for the bearing caps, maybe set those aside?

Good idea on the caps. I was looking for some a while back.

You want ‘em? $100 plus shipping. That’s what somebody’s going to ask for a set after they sell you a block without any. Let ‘em take up space in your garage, not mine. I think it’s ridiculous to sell (or buy) a block without them, or to offer the caps for sale after the block is sold. In my opinion and teaching, the caps are part of the block and either is worthless without the other.

You are absolutely right; when the new guy gets the caps, he then has to spend another $250 to have it line bored. Or he doesn't know this and his main bearings seize up after ten minutes of running.

Well, my opinion, that gpw block is way too far gone, especially you may need to spend a bunch more to get her to work right, .080 over, heli coils, no ser number, broken ear.

As far as a block with no main caps, worthless? I would rather spend a grand getting a center line job than dealing with something that is past its time.

i have MB 2 blocks for sale, 1 with caps to use on the one without caps, no cracks, decent block, nobody wants it, yet I see replies about "thats great, somebody is making repo blocks" or save it there is not many left. you see the issue with the last batch of china schafer can blocks, think the new ones will be better?

I just bought a mb block,, no caps, turns out it was a slatty block less than mb104xxx. it is in the shop now, I took the caps off the one that is for sale above. So worthless depends on what the block is, on the other hand i will scrap the above 2 blocks shortly as they are in the way, after all they are worthless.

I also have a gpw block,, from chucks toy, you can find the ad for it from years back in the for sale section, chip off the boss for one of the two middle cam drill points, nobody want it, worthless i guess. on the other hand, probably a better canidate for rebuild than something way past its time.

I guess it’s something in my raisin’. I cannot imagine how a block can become “without caps”. Not in my world, anyway. Others may be more careless. Even every block I ever scrapped had its caps with it. That goes for connecting rods too.
True, what you say. The time comes when every thing has reached the end of its useful life, and we need to let them go. I think this one could be saved, but it would cost a LOT, and a lot of what has already been done would be wasted. The PO spent ‘way, way more on this block than I gave him for it. What a shame. Also a shame is the facts that a lot of expensive work was done poorly, and would have to be re-done, at more trouble and expense than the original repair should have cost.
It’s still here, my friend came and removed the new valve guides and left it with me to be scrapped. I feel sad every time I walk around it. I guess it’s time to throw it on the scrap trailer.

If you were closer I’d buy it and put all my bad f parts on it for a display.
