And was the oiling system different?

In that year there were differences and for sure in 1954 they changed to a modern full pressure oiling system. No 216s were made after 1953. The 216s and early 235s used dippers on the connecting rods and spray nozzels to enhance the rod lubrication at higher RPMs. The oil pressure on the 216s and early 235s was a lot lower than the full pressure motors. The connecting rods did not use insert bearings but had the babbitt attached directly to the steel rod. Here is a good link with lots of information: Chevy Six features

Full pressure lube, a little more power, and higher RPM's. That is why I think most people change them out. For the higher speed driving. the 216's you cannot run at the higher speeds with the stock set up. I run 3 216's and 1 early 235(low pressure bored out version of 216 developed for WW2 I believe)
They do everything I need them to without issue. I hear the "pounder" nickname and I thik it refers to the clanging noise for out of spec bearings, I am sure someone can elaborate hear that has a litle more knowledge than me. | | | | | Joined: Feb 2010 Posts: 45 New Guy | | New Guy Joined: Feb 2010 Posts: 45 | | | | | | Joined: Jun 2009 Posts: 49 Wrench Fetcher | | Wrench Fetcher Joined: Jun 2009 Posts: 49 | I'm ashamed to admit I was one of those guys who said my orig. rebuilt 216 was fine. I used the truck alot but was never happy with the 216. She now has a nice full pressure 235 which is one he!! of a nice motor. | | | | | Joined: Nov 1995 Posts: 5,716 62401 | | 62401 Joined: Nov 1995 Posts: 5,716 | Just be advised that if you are contemplating removing a 216 and replacing it with a later (full pressure) 235, it is *not* a form/fit replacement. There are some mods that need to be done in order for the 235's to fit without butchery of the radiator shrouds. Check out our Tech Tips for more info on this. Not hard (I did it  ), but still something to keep in mind. V/R John
