Picking up a spare motor 370 long rod for 300 bucks. Questions on setup


Recommended Posts

So I found a sweet deal on a 370 long rod motor the guy just wants to get his money back for the hot rods crank he put in it and hates to see it sitting around. I've been looking for a spare for a while now so it works out good! My question is with the long rod motor is the only thing different I need is pistons? I am planning on putting my 392 cub cylinders on this bottom end so I'm not sure what pistons that would require or if it will work or not. Anyone ever built a 392 cub long rod? Thanks for any help 23ab615b70d58c20eb908bd89c8f8e0f.jpg

Wsm makes a direct replacement piston for a long rod stock stroke. We can get those. Our pistons are a 6mm offset he needs a 5mm, like a 795 wiseco but in 68mm.

I don't see a 68mm 795 Wiseco piston in that Wiseco link.

Check the link I posted to CP's site.

Thanks Bill!! I don't know why I didn't just call u before I posted here!! I'll be getting in touch with you soon I'd like to get the Cubs replated and some clean up porting to get all the casting flaws taken care of and then set up with the pistons I need for long rod

Your correct they have it listed as the piston to use and with a .012 gasket. So just figure the cylinder is same height as stock but .008-.010" lower than stock with a .012" gasket, the rod is 5mm longer. A 573 is a 6mm offset, so the piston would be give or take .032" further in the hole at tdc. A very shallow stepped dome could be cut so the squish wasn't in the high .060s-.070"

You see on the smaller bore cub they use the 795 piston. I know they don't make a 68mm 795 but it's what you would use if there were one. Either in zilla killas case we can do either piston.

I'll put my trust in you bansheehp you set my last set of cylinders up absolutely perfect and the thing is runnin better than new!!
