I am about to do a rebuild on a 1955 261 and have been reading up. The information I find is mostly pertaining to '58-'62 261 engines which leads me to ask a few questions.

Is this '55 261 a full flow oil system? It does not have the 3/4" holes for the oil lines.

Is it possible to use my original '48 216 oil filter if not a full flow system?

Can I run a hydraulic cam/lifters in this '55 261 engine?

Thanks for you input.
