OR, modify the OLD and first 235 that came with a tall side cover, for full pressure oiling. Then it will look just like the original motor.
You'll need a really good machinest friend to make the 55-62 drilled crank fit the old block and some plumbing mods. But, it's a lot of work and not cheap, plus compression will be much lower than a later 235. I'd keep that 56 235 and make it look stock, very few people will know the differance.
