Another 302 ID question.
 

I have an odd one here, hope someone out there has the answer.
Purchased a 77 mustang recently with a 302 in it. It has a T-5 transmission that according to the salvage yard markings is from a 93 mustang. The bell housing and starter appear to have came with the trans.
I assume then that the flywheel is a 157 tooth 50oz counterweight unit. I know that a 77 302 would be the 28.2 oz

It has a slight drive train vibration, but not as bad as I would have thought it would be if it needs a 28.2oz counterbalance.
The guy I got the car from had owned it about 6 months and had not driven it a lot and had no idea about what was done to it prior to when he purchased it.

Long story even longer, I pulled the started to check the casting # and low and behold no casting number, the ridge where they go was not even there. There was a date code there but it was running vertical to the crank in lieu of horizontal with the crank.
2D24,- 2nd year, April 24th. But without a casting code I have know idea of what decade. Checked all over the block but found no numbers any ware .

Anyone ran across this before? I really don’t want to pull the engine just to get the pan off and get the numbers off the crank.

When is the vibration accuring? On acceleration or deacceleration, idle??

mainly on deacceleration
