273 302 318 340 build
Since you mentioned that you are considering other options, I have a '68 340 available. I just honed the cylinders when I built it in 1975, so first oversize is still available. It has not been cranked since it was pulled out of my car almost two years ago, and after 40 years since the rebuild you would certainly want to go through it again. All stock internals except it has the old purple shaft cam, Crane lifters, double roller timing chain, and high volume oil pump. Stock "X" heads. Crank has been turned .010" undersize. Direct Connection electronic distributor, but that is also 40 years old. I have the stock cast iron 4 barrel manifold, but it is not installed on the engine. Everything is currently in Chicago if you are interested.
