on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Jan 2008 Posts: 77 Wrench Fetcher | | Wrench Fetcher Joined: Jan 2008 Posts: 77 | I have gotten alot of info from this site and have a couple of questions. I understand that my 53 5700 has a 58 235 which is longer than the original 235. Jim Carter has an adaptor plate for this swap. I don't understand the reason for the plate. Isn't the pump mounted into the blockface? I'm not at home, so can't look at the moment. Trying to decide the best, not easiest, way to proceed-- new shorter pump, or adaptor plate with original pump. | | | | | Joined: Mar 2004 Posts: 874 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 874 | The original style pump has to mount in a higher location on your later 235. It becomes obvious when you have the parts in hand. It is the best option in my opinion. I just installed one on a '55 235. | | | | | Joined: Feb 2003 Posts: 1,377 'Bolter | | 'Bolter Joined: Feb 2003 Posts: 1,377 | If its the same adapter I used on my 37 with a 57 235 you will have to drill two holes in the block and mounts a 54 on back water pump on the later 235,I ran a shortened pump for 7 years but could not use a stock fan so when the pump broke and went into the radiator I bought the adapter. I had to remove the grille shell to drill the holes due to space limitations but I am glad I used the adapter plate.

It looks like the best way to go is the adaptor plate. Doe this then use the later pump, or the 216 pump? Thanks for the help and nice engine Ghostrider-- I saw the plate on yours. | | | | | | OLTrucks Unregistered | | OLTrucks Unregistered | I uses the 216 (or 54/551st 235) pump | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | The adapter can be used with a 1941-52 216/235 pump if you want the 5/8" wide belt or the 1953-54 pump for a 3/8" belt.
