318 bored 60 over

[CHL2T]

Howdy all, I have some questions regarding my engine.
Here are the stats, 74 318, bored 60 over as verified by the pistons (block was bored to those specs before I bought the car) I had it tanked, roundness checked, magnafluxed and the bores honed before I personally rebuilt the thing using all 340 internals, crank, cam, rods, lifters, pushrods and oil pump. There was also a oil filter adapter on the engine when purchased which when viewed from under the car looks exactly like a 340 oil adapter. The thing is/ was frighteningly fast and I scared myself a few times before wising up and taking my foot outta the carburetor

The question is....What would my displacement be considering the 60 over boring?
What's with the oil adapter, would someone pull it off a 340 and put it in a 318, or do you think it was aftermarket? (with headers it sure makes it easy to get at the filter however)

Long ago, while driving on the interstate, the harmonic balancer broke, and on it's way off, it snapped about a quarter of the woodruff key off of the crank. When I installed a new balancer, the thing basically fell onto the crank with no pressing with the bolt whatsoever. I put loctite on the threads and torqued it to specs. Works fine with no unusual vibration.

If I was going to replace the woodruff key, is it possible to do it without pulling the engine/ crank? Or should I leave well enough alone and check the torque of the bolt and call it good?

Thanks for the input

The question is....What would my displacement be considering the 60 over boring?

(            Area of circle            )*(stroke)*(# of cylinders) = # of cubic inches
(((3.91 +0.060)/2)^2*(3.14159))*(3.31)*( 8 )= 327.78

Hopefully I got that right.

I agree.

Bore x Bore X Stroke X .7854 x # Cylinders = 327.78 ci

One of those 90 degree oil filter adapters was on my 318 with stock exhaust manifolds. I was trying to eliminate it because the 3 rings and gaskets were expensive to replace, and just use the regular plate.    I ended up having to change it all back because headers will not fit without it. So basically, you only need it if your headers go over the block's filter area. Stock manifolds can either use it or not.

Thanks guys, Now I know what to tell people I got under the hood, or mayhap I'll just say its "close to a 340"
 If I say "I got a 327" it may cause some confusion
