S&S Cycle 136" Crate Motor

[Ohio HD]

S&S has an M8 crate motor, a 136" complete ready to roll in all blacked out. Just guessing by the dyno sheet they're probably a little conservative with the compression. That has been their typical MO with crate motors in the past. But it still looks good. I also see they have the oil feed, return and vent in the case.

But I've seen our resident tuning guru rigidthumper do a little better than that with his 131" lower compression big bore M8.

That's the 49 state version with cat exhaust (i try to avoid those limitations )

Wish they had one for the M8 Softail.

You can buy the components and use them in your cases...
