25.5 m/sec sounds... difficult to keep together for an enduro engine.

I'm sure the cams will make power up there, the other question is will the bottom end stay together up there.

Yes, that's what I am starting to think. I was looking at the BC crank because it's full counter weight crank. I traded some parts for this crank, so I don't have much money in it. Which would be better, stock and C78 cams, or shorter duration cams and keep RPM down below 7200. Stock stroke at 7500 is still 24 m/s. Still not a great number.

The general advice of some of the KA guys here is keep it below 7200 and/or put a good damper on it if you want the thing to survive.

I would think one of the hotter off the shelf KA grinds that's a little less rowdy than the C78 cams would probably do just fine and not hold the engine back.

you'll get lope with the C78. It's really an all out stage 3 type cam. bc cranks come with stock stroke also. u don't have to get the stroker one

nvm. u already have it

I'd run the stroker and keep the revs around 7000-7200 with a cam that will work there personally.

You won't be able to fit the oil squirters with the larger stroke crank. I had to get mine modified. Ben recommends their DLC valve buckets with the C78's.

What did you do with the dry sump pan to make it fit?
