look in the tech section! what number is on the heads

 

***uming it's all as it came from the factory, it's either a '52 or '53 303, according to the valve covers and the intake.

 

What are the raised numbers on the top of the bellhousing part of the block back by the dizy?
555641
561747 all of these numbers are 303
563922

if not any of the above PM me the numbers you find

 

I'm saying 53. 53 was first year 4 barrel, and it should be 12 volt. Numbers are stamped on the block, on the deck surface of the driver side head by the rear exhaust port.

 

'52 was the first year a 4bbl. was available, and in '54, Olds went to a larger bolt pattern for the carb, so it's either '52 or '53.
