I can go for a set 3.504" or a set of 3.484". Whatever is best to complete the buy.

I'm in for a 3.485" set, assuming that will help complete the buy.
Thanks, Rob!

This is the current list of people wanting these pistons. I don’t know if this will be enough to get them to make a run or not. I’ll report back next week.

Pro-Tru Chrysler 225 Slant 6
Compression height - 1.625
Wrist pin - .901
PT112H84 - $650 per kit
PT112H104 - $650 per kit
Rings XX style ring 1.0 x 1.2 x 2.8mm; Gas nitride top ring; Napier scraper 2nd; Flex-vent style oil set

Roll Call:
Rick Covalt - 3.504” x 1
Greg Ondayko - 3.504” x 1
Wayne Venable - 3.485” x 1
Lou Madsen - 3.485” x 1
IdahoCarson (FABO) - 3.504” x 1
Matt - 3.504" x 1
CJ - ???

I ordered a set of the cast crank rods to get us to the minimum required. I’m not in a position to do that for a set of pistons that will also set on the shelf until my estate sale…

Hopefully Adam will be able to make a run with just 5-7 sets. More to follow.

Planning on Clay City at this time, so bring my Rods and Pistons there if possible. If that falls through we can work out shipping.

Thanks,

Greg

Update for folks like Lou who originally wanted the smaller size. Reply from Adam below.

BLUF: The smaller 3.425 and 3.445 are shelf stock items, but we can order them through this group buy if preferred.
Quote:
PT112H84 is 88.50 bore size = 3.484

PT112H104 is 89mm bore size = 3.503

PTS536 Series , 3.425" & 3.445" yes these are a current shelf stock.

The larger ones I reactivated would be considered a custom since they were discontinued.

You can add the other part #’s to you order if you like.

Is it too late to get in on a set?

I have already got this batch in the works, but you can reach out to Adam Thornton @ Wiseco Pistons to see if you can still squeeze in a set.
