Need Some Advise

My fingers were typing fster than my brain was functioning...I left off the "n't" ...Orange isn't a good color for a '68 340. A '68 340 should be RED. See if you can see the red peeking through anywhere, and if there is a 340 cast into the side of the block.
Also take a peek under the car on the drivers side. If the car has a '66 or earlier 4-speed there will not be a machined ID pad. If there is a machined ID pad with the VIN stamped into it it will most likely be the '68 4-speed as well.
Also both my old '69 Swingers had no paint on the bell housing, just turquoise hosed around the edge. If it is a bare cast aluminum bell, you will have the big flywheel and clutch.
