Inliners International Forums General Discussion Engines GMC 270 Oil filtration

Hi there,

I'm doing some minor stuff to my engine and was wondering about my oil filtration, does anyone know if this is full pressure or by-pass?
Also, can i change this to a modern spin-on filter somehow?
GMC 270 1955-1962 according to numbers by the distributor.

Maybe this will help you.

There is an article in the 'Tech Tips' on full flow conversions, I have done it on some of my engines and it is quite easily accomplished.

Thank you for the tips!
I have read the article in techtips, but i am unsure on:
1. where to drill
2. what to do with the oil pipe up to the head

I understand the need of taping and blocking the passege and the drilling and the remote filter, but then what? =)

Confused? You still need the pipe at the front of the head to feed oil to the rockers from the now filtered oil gallery. Many make that about a .060" for the feed. If you are still using the overflow tube on the rocker arm shaft near the center it may not make any difference. I now run a lot of pressure so I control flows to different parts of the engine with orifaces
The old bypass oil filter emptied right at the distributor which sprayed at the gear. I still do that with a line tee-ed off the rocker line. I solder up a fitting and drill a .035" hole at a slight angle aiming at the distubtor gear.

Send me your email I have pictures of my engine on a stand with the hoses and filter.

Thanks for the clarification.
And yes, i'm more confused than usual.

I was looking at a conversion walkthrough over at oldgmctrucks.com and it made it alittle more clear, i would appreciate pics though, thanks!

Here are the only pictures I have. Imagine me not taking a dozen or so.

Easy mod to do. Here's another way to do it:

Great pics everyone, thanks a bunch!

I am contemplating of doing this, i only feel slight hesitation on pulling the engine.

Should it happen i am going to do a complete walkthrough with all steps and pictures for future references.
