I would go with a Circle "D" I have not heard one bad thing about them.
3400 stall would be too much stall for your combo IMO.

Circle D is great. I ripped one in half and had a flash fire. Chris the owner did everything correctly to rectify my situation.

I bought a 245 MM ( 9 3/4") triple disc 3600 stall from Circle "D", but mine is not running yet.
I need the higher stall because I am only using an inline 250 6 cylinder for my power plant.

Well after almost dying in 2022 due to china virus hospitalization I'm back on track and but still on the fence after so rudely being interrupted.

Circle D rep recommended a 2800-3000k stalled pro series
Diameter 10.25"(258mm) triple disc, lock up.

Emailed tech support at yank and no one got back to me so is what it is, was looking at their S/C Series 3000 stall 10.5" o.d. lock up.

Anyone care to chime in with experience on this application?
