A lot of people have been asking for these. We finally received some.
Just listed them. Haven't taken a photo yet.

372 372XT 390?

Waiting on @Mastermind 's permission

I think we need to build a kit to retrofit the 372XT back to the old school XP version.

Is the 066 kit the one that was actually manufactured with Randy's modified numbers already cast into the cylinder? (I may be mistaken, just asking)

I believe so, but hell I could be wrong too

The 064 cylinder base match up with stock 064 case without modification?

 

[Brewz]

numbers?

I did a thread on these. I'll see if I can find it.

The jugs are the same, except for the bolt patterns. When installing on the 064, be sure the transfer bulges clear the case....

Here's a thread Justin did on installing one.

The XT conversion would be nice, but either would do for me. I've got them both. what about 385/390? I'm guessing the 066 is a much better seller? @Mastermind @Gentleman

 

[Mastermind]

I'm not opposed to doing a ported 372 and a 390XP.

Better get the numbers from O:cry. I heard that was the perfect example of a hotrod saw that has never been defeated in a race.

I still say this is pretty cool. Not a lot of actual bolt on performance parts for saws.

Poor guy.

 

[dolmarkid]

imo the xtorq is a pretty good saw when ported

I worry that the crank would last though Mike. The guys that could stumble across these parts mostly can't file, can't tune, won't use fresh fuel, and sure as hell ain't gonna run the saw on good oil at 32:1 like a ported X-Torq needs.

I'd be be all over a big bore 372xpw custom cylinder. I think it'd be downright awesome if they added some clay or whatever is needed in the areas of the mold that would cause the areas where people port heavily to be significantly thicker so more could be done to the cylinder to modify and open them up.
I love the idea of the Wiseco type machined forged pop-up piston for a "Magnum orSuper" style kit
Mo-power.... can't ever have enough
