Re: 327 engine
That casting number comes up as a 1968-69 302 from a Z-28 Camaro with either 2 or 4 bolt mains..

Re: 327 engine
Got me on that one!? I have read that the 302 is the same as a 327 except it uses a 283 crank. Which gives a 3.00" stroke. I guess if all else fails you can measure the stroke to see if it is a 302 or 327?
What sites did you use to get those numbers?

Re: 327 engine
Oh I see.. lol
 I suppose the block is the same for all three.. Only difference is the stroke.
