What's a 928 & 950?
How much hp & torque do they put out?
The 928 is 71mm stroke x 74.5mm bore. 193hp and 126 ft#'s at 8100RPM. Dyno sheet cut off after that. UBR built. This was with 12-9/1 heads, stock 38's and Jaws pipes so there is still another 1000 RPM to make more.


950 is stock stroke with 77mm bore, no dyno data

are you 100% sure that they will work on my 98 809? and the next thing what size pistons would they be mark.
779 cylinders will fit and bolt up to the 809 case but not the other way around. Pistons are just standard over bore size most likely.

Carbs will swap right over. I've never ran the 830 so I can't say much about it.
