Thanks for your input Jim! .430 lift at lobe seems like a little much, even with the 1.25 rockers, I'm guessing you get around .560 at the valve? Which springs are you running? I'm trying to stay away from CB650s and the like
Intake valve lifts (actual with 650 springs):
1: 0.562
2: 0.565
3: 0.575
4: 0.560
Exhaust
1: 0.567
2: 0.575
3: 0.584
4: 0.575
Spring pressure (@ seat / nose)
Intake
1: 165/400
2: 170/400
3: 165/400
4: 165/400
Exhaust
1: 165/400
2: 165/400
3: 170/400
4: 170/400
Most springs went to coil bind @ 0.660-0.670 when checked in head on drill press with dial indicator attached.

If you're thinking FK8/FK10, the shop I used to work at had several customers change them out in 2276's/2332's for a Crower 61005, and completely change the driveability of the engines. I had a similar experience in a 1776 with Engle's cookie cutter W110, and a 61004. You can check out their specs at https://www.crower.com/cam-card-finder/ and type in the model number.

FK8, it will not disappoint

check out fk44 specs, many like it better than the k8 choice. Still very streetable.

my 2333 has the slipper skirt cast AA pistons dished in a bathtub shape. It looks like he got 7cc from the pics. I don’t know if he could have got more.
with 7cc’s you’re at 10.2:1 pretty decent.
This Cam is huge, reliable, (look at the year) and perfect for a daily! Check the specs. ;D
Not sure how it would work N/A.
