It's complete except for the oil filter there's two passages on the left side of the block very small 1/4 I'm guessing . Where the steel lines would go for the oil filter . I purchased a remote oil filter kit that uses 1/2 pipe fittings . What should I do. I don't want to get crazy and bore out the block | | | | | Joined: Feb 2001 Posts: 1,094 'Bolter | | 'Bolter Joined: Feb 2001 Posts: 1,094 | Post the numbers on the side of the block so someone can id the year of your 261. I'm not sure, the early ones may have had the small oil lines, however the later engines had 1/2" oil lines. There is a dowel in the side of the block that needs to be pushed in to make the engine a full flow through the filter. If you look in the tech tips you will see a conversion process for full flow.

You will need reducer fittings and a restrictor in the inflow line in your remote filter.
Jim Carter now lists a remote by-pass filter head for a spin-on filter. This set-up seems to have a by-pass restriction built in.

It's just going to be a weekend driver . So I'm thinking about buying a beehive oil canister . Throw the spin on kit in garage for future use on something else | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | Any chance the block casting code is 3738813?
| | | | | Joined: Nov 2011 Posts: 8 New Guy | | New Guy Joined: Nov 2011 Posts: 8 | I Checked the numbers on the block 3733813 are my numbers it looks like the motor uses the bypass oil filter the 1/8 pipe threads are used on the ports for the filter . I could try to find a original bypass housing or beehive for what I'll be using this motor for will be just fine | | |
