If you want the high compression kit you better buy it I was looking for this recently and it is discontinued across the board. I ended up with an over bore kit which is due to arrive Amy day now because I had ordered just before I saw this. If you want a 4 inch sleeve kit grab any that you can find reliance own powermax now and they only make the overbore.

You mean 50 years

Usually they are oiled and wrapped in an oily paper but 50 years is 50 years

The overbore kit is about $600 that kit was listed for $915 when it was discontinued.

That kit will work for a WD45 engine, right?

It will fit in a 45. I just put one in mine. The question I have yet to find out is if it's really too much compression for the smaller 45 crank. I've heard stories about crank problems with M&W's and these probably put out the same or a little more power than those do.

I haven't got my engine back in the tractor yet.

Down the road you may not find another kit like this. Hopefully Reliance makes another run of these, but that would take a lot of orders, and not too many people want to pay an extra $300-$400 for a kit. Most people with a D17 order a D17 kit, they don't even think about trying to put in a 175 kit and there were only about 1000 175 gassers made.

When I ordered my kit the other day I asked what it would take to get reliance to make another run because I knew from this forum there was interested the official word I got back was when it was powermax that would have made a difference but reliance just doesn't see the demand and won't as long as the overbore kit sells well.

If you're wanting a real hot rod, you'll get more with a 226 and WD flat tops than the 175 pistons. Me, I was still looking for something to farm with too.

Too bad to hear about Reliance. I know they could sell the kits and make some money, but I suppose they figure they can sell the 7.25 kit quicker and easier.

The one I'm building right now I want to be close to stock.  It will be used for hay'n, raking, small baling, yard work, etc.  The next one I'm doing I want to be competitive in stock appearing pulls some day.  I have an over-bore (4 1/8) sleeve/piston kit for it.  I just might pull the sleeves from the other block, get them checked/honed and use them with the 4 inch pistons.  Or just use the other block and leave the sleeves in.  Actually, that sounds like a better idea, I think I'll do that and save the other block for the puller.

Powermax calls their 8.25 kit "LP / Hi-Octane".I know the 8.25 kit is (was) only available in 4" and the 7.25 kit is 4.125". I'm wondering how much the 7.25 kit (that is available for ~$400) would dyno less with the added cubic inches. There is also a little less stress on the crankshaft, rods and bearings with a little less compression.

I was the original bidder ($399) on this, but with all the variables; age thing, no warranty, rust/corrosion possibility and we aren't even sure someone hasn't carefully opened it up, robbed pieces and the kit isn't all there. (There's an old saying about buying a pig in a poke... - I like to be able to look at what I'm buying!) I guess I'm out. I was willing to take a chance ~$400, but I'm not that much of a gambler.

It's up to $430 now and you know it will go crazy the last minute! I'll buy the 7.25 kit, have a little less power and hold onto my $$$!

$542.00 ending bid

Not me, probably should have. Seller sais he would accept returns for 14 days. Hate to open the box and see worthless sleeves. Maybe if I had a tractor for them, but I don't. Just a someday hope.

I bought them. WTH, I had a limit, and the kit is worth a shot for the money.

Cool glad to know someone who will value it was the winner.
