old oil filter or modern one.

[DutchEdwin]

Rebuilding my P27 V8 I would like to know your opinion on this one.

The oil filter on my 1955 P27 V8 has a canister/cartridge inside. I can keep using this one and try to find a replacement filter or switch to easy to find modern filter.

Question, I would like to keep the car as original as possible. So I would prefer the old cartridge type filter, including the oil dripping when exchanged. But is it as good as the new types?

Look at the tread from hothemihead for the adapter http://hotrodsandhemis.com/[/url] at tab "rebuilding a Hemi"

and from

Whittakers, at http://hotrodsandhemis.com/ For installing a modern filter.

Second question, the check ball valve.

I've read that the original old system the ball check valve could let oil through the system without going through the oil filter. So the ball check valve in the main oil supply galley should be removed and an oil filter bypass plug (which is a must if you're using a modern filter) be installed (see picture 4 and 5 beginning from the top). In my engine, only the ball and guide cylinder at the main bearing are there.

Is this nessesary, or is the check ball valve as good. And it so, can anyone give the spec's of the spring, outer diameter, wire thickness and lenght?
