Well the answer to the first portion of the game is.......

(Drum roll please....)

293 cubic inches (I'll accept 292)...

It's a C5 289 block, .030" over. Crankshaft is a new steel crank at 2.870" stroke. (4.030/2)^2 * 8 * PI * 2.870 = 292.8

Tom Cimino, the math should be:

Deck height - rod length - piston compression height - 1/2 stroke.

8.195 - 5.700 - (2.870 * .5) = 1.060" compression height.

Normally, at this compression height, the oil rings do intercept the wrist pin (not a problem), but since the ring pack is so thin, it gets it up out of the way.

So, there are a couple of guys who were dead on with the displacement:

G Edmonds
Jac Mac
DWRAT
jhirasak

Lots of guys guessed 289, which is close, but going .030" over adds a few cubes.

Congratulations guys, it's literally the final four....LOL
