Here is what I have:
I bought a matched set of low hour case off ebay a few years back, no damage no repairs, then case bored to fit a big jug 330.
I ended up never using them and buying a few diffrent PV set ups and they just sat around, I have no future plans to build a 330 or a 350 I am currently selling one of my 310 PV jugs.
So these need to go.
Sleeve clearance size is 83.1mm as shown, stock is around 76-77mm
shock cylinders and 310 cylinders will also work in these cases, the cylinder is centered by the dowell pins on the side and not the center bore.

I had a error in the listing that was brought to my attention the cases are bored for a 330 at 83mm you need 86.75 to clear a 350 from what I have been told.


They are black so either 85-86 atc or 88-89 trx ? They look very good you will as soon as I get the pics up.

I want $425 shipped or best offer pretty soon they will be on ebay

Some of you a asking about bearings,
I have all the bearings and retainers.
They where removed when the cases where bored to prevent debris from contaminating them.
I also stock new bearings a set of OE and aftermarket mains and some of the trans bearings as well, The old ones where good so I saved them, but I was going to replace with new.
I will also throw in the center case bolts as seen in pics they are new as well.

I also have a set of gears w yukons, and a hinson clutch basket posted.

I am updating the post, to let everyone know these cases are bored to fit up to a 330 but not quite big enough to fit a 350 jug unless your 350 jug will clear the size shown
they where bored for my CT 330 to drop right in to. I thought 350 was the same clearance but have been corrected.
"also works for stock cylinders and 310s"
