Looking here:

http://chevy.oldcarmanualproject.com/models/engine.htm

I came up with Flint 1956 auto with powerglide (F 56 Y)
56 Corvette is FG or FK depending on transmission which are v8.
55 and earlier Corvettes with 6's had code YG

Hydraulic lifters were used on powerglides auto trans and are good motors same to 1962. I was going to go with a 235 also but after I check on how much everything cost it was cheaper to go with V-8. Lose the tranny and put a turbo 350 or better yet put a 700R4 behind it, Patricks or Chev's of the 40's have adapters. Here is some good read on 235's.

This block 3837004 Chevrolet was used in 55-57 and could be 235-261

Just because the block was used with a PG doesn't mean it was never used for any other truck or car. It means it had a block modified for Hydraulic lifters.
F = Flint 56 =year Y = w/PG. So you have a 56 hydraulic lifter 235.

The significance of this block is that only P/G engines were drilled for hydraulic lifters prior to 58. 58 and after were all drilled for hyd. lifters. Its a hard to find block if your doing a number match resto. The block mounts changed in 58 and again in 60 so you can't use them for a 56 rebuild.

Unless you owned the truck for its entire life there is no way of knowing if its original. For some reason everyone thinks if its a 235 in there it must be original. The failure rate on these was very high. No oil filters and next to no air filters made for changing motor often.
