I'm going to test my memory here. I pieced togther a 360 many years ago for a friend of mine. The basics of it were:
4.04" KB 190 pistons, the compression was around 11.5:1
Ported cast iron J heads with Manley 2.02"/1.60" valves
Port matched Edelbrock RPM Air Gap intake
Mighty Demon 825 carb
HVH 2" Super Sucker spacer
Solid F/T camshaft 252/258 @ 0.050", 1.6:1 Crane rockers, Valve lift was around 0.585", 108 lobe separation
1 3/4" x 32" 4 into 1s with a 3" collector
It made 495hp @ 6300, 471 ft/lbs @ 4800
We ran an 8" convertor that flashed to around 4800-5K from memory. It ran low 11's at 119 mph, trans was a A904 with a factory gear set

I've got a 360 of my own sitting at home that's similar, we built it up using parts we had lying around:
4.03" KB191 pistons, the compression is up around 13:1 (to be honest, I've not calculated it)
Ported cast iron truck heads, 2.02"/1.60" chevy Ferrera valves
Heavily modified M1 Intake
HP Holley 950 that I borrowed for the dyno test
2" open spacer with a 5 degree shear plate
Howards F/T camshaft, Crane 1.6:1 rockers, 268/276 @ 0.050", 106 lobe separation, Valve lift was around 0.686"
1 3/4" headers we had lying around, they were out of a Challenger, no idea who made them.
That engine made 520 hp @ 6800, peak torque was around 490 ft/lbs @ 5200 or 5300
If I wasn't making some changes to that engine, I'd throw a 8" convertor that flashes to around 5300-5500

If I was racing with a 2 speed glide, I'd have the flash speed higher again

I hope that gives you some insight Mike

Cheers
