The 360 build that has more turns than Willow Springs

As regard those KB107s
I have those in my 360, which gets abused every time I fire it up, since 1999.
IMO the ring gap spec of .0065/inch bore, "for street", is too tight. I had an impossible to solve overheating issue, right from day one. The Skirt spec of .0015 to .0020 may be ok, IDK; but my engine builder refused to set it that tight. He gave me .0035
I nursed her thru the first summer, then tore her down.
I had the skirts rubbed out to .0040, and installed a file-fit set of rings at .0080 ring factor on the top, and .0070 on the second. I left the oil ring gaps alone at .0065 spec.
That immediately solved the overheating, but on cold mornings, I could hear the piston slap.
I solved that with a hi-flow 195 stat that actually runs at 205/207 at the stat house, and she is underdriven just a bit.. and, I give her a lil time to come up to temp, before beating on her,
With OOTB Edelbrocks, TTIs, an AG/750DP and at 11/1 Scr with a 230/237/110 cam, car has gone 93 in the Eighth with 3.55s at 900ft at 3457 pounds, me in it; on the only one completed run of four it ever made..
To say I was ecstatic is an understatement.
After I solved the heating issues, I got nothing bad to say about those 107s.
By the way, I have consistently run a Q of .028 to .032 on those, with factory rods, with no touching, with the rev-limiter set to 7200. Currently my pistons average .007 above the deck. They fell in at .012 below. So the total deck-mill is about .019
One Time, I ran 028 gaskets, but they barely made it thru the summer, as on teardown, the fire rings were seen to be almost into the valley. But I admit, I was running about 195psi at the time.
Yes, for the first five or six winters, I pulled that 367 out every fall, and swapped in a 318 for the winter; then freshened the 367, for a May-long install. Four of those winters, I caught stuff that would have cost me a lotta money to fix, if they had matured. Most of the gaskets were reuseable, so mostly it just cost me time.
And I learned an awful lot about what doesn't work. and a lil about what does. For example I reused those 039 Fell-pros a couple of times, and got away with it. I still have one used pair hanging in the rafters..... waiting for a project.
But
Those 107s IIRC are just 502 grams, so, I had to rebalance everything.
I'd have no problem using those again. Mine are plus 040.
