Took the head to the machine shop and they fixed it up. looks like it had previously had a thread repair (heli-ciol) that came out with the last plug.
So heads on.

Ok so now for the guess work.
Here is the specs lets see who comes closest before I get it on the dyno, everyone please post a guess at HP an Torque.
It is a 327 small block Chev, 60 thow over.
Had the deck done down to 15 thow.
Installed the Cometic 27 thow gaskets.
Has the 1960's 461 Corvette fuelie heads with 1.94 and 1.50 stock valves, I cc'd these heads at 64 cc.
Has the roller rocker setup with the stud girdle.
Has 2X4 600 vacuum secondary Holley carbs.
The big dual high rise intake.
And basically the straight headers, they have the 3.5" cherry bombs on them.
One not .. I ended up removing the windage tray due to a dipstick clearance issue.
And here is the cam card, its a solid lifter.

For a hint the stock 327 Corvette power ranged from 210 hp to 375 hp depending on the choice of carburetor or fuel injection, camshaft, cylinder heads, pistons and intake manifold. In 1962, the Duntov solid lifter cam versions produced 340 hp (250 kW), 344 lb·ft (466 N·m) with single Carter 4-barrel, and 360 hp, 352 lb·ft (477 N·m) with Rochester FI. In 1964, horsepower increased to 365 hp (272 kW) for the now dubbed
L-76 version, and 375 hp for the fuel injected
L-84 respectively, making the L-84 the most powerful naturally aspirated, single-cam, production small block V8 until the appearance of the 385 hp (287 kW), 385 lb·ft (522 N·m) Generation III
LS6 in 2001.
Note some of that is copy and paste from Wikipedia.
Also note in the 60's General Motors horsepower and torque numbers were notoriously under rated for insurance reasons.
My guess with the open exhaust, bigger cam, and huge intake its a bit more but I won't say a number until I get a dyno sheet, I would rather hear what you guys think.
