Default Re: Block identification

yes 33-34 not 35. The 35 block is the first year of the front vent tube in the lifter valley. The block would have an opening in the oil pan rail for the vent that has a cover as part of the oil pan. The 32 and maybe very early 33 block have threaded opening for the coolant drain petcocks that are vertical. The 33-34 engine blocks are identical.
