Oil filters on flatheads

Never even heard of that motor! i have a feeling it is not only because of the way it performs, definitely not a high winder. the motor is revving pretty high at 50mph and running out of power, at 60 mph it feels like it is going to blow up! It feels like it is geared super low and needs another gear.

That's just flatheads, it's not turning near the rpm you might think it is. Check the gear ratio and see what you have in it, but I would guess it's not that low of a rear end.

The rear axle should be marked as to the original gear ratio. If not, it is fairly easy to check.

My car is a 36 with no exposed driveshaft. I know how to check it on a normal car where you can mark the driveshaft and count the turns vs the tire turns to get the ratio. How do i do it on this car? I did not see anything marked on the rear, but wan't really looking for it

I scrubbed it with break-clean and worked on it for a while with rags and plastic scrapers ans I do not see any numbers at all. I only did the bottom, because you pretty sure that is where it is. No chance it could be on the top side on that same rib?
So what is the second easy way to figure it out?
 
My 59AB apparently never had a filter. Still doesn't. Has 35,000 on its rebuild and still has good oil pressure. I think key is frequency of oil changes and to a lessor degree, maybe the quality/kind of oil you use. Mine used common Penn HD 10w-30 year round.
 
Yes, I saw the pic upper top left as you said.That pic could easily be the top or the bottom, but you said bottom so that is all I did. I did miss the link. So now looked at that thread. My plug is already out of the ****** and rear because I have drained all the fluid in both and will be replacing with new fluid from MAC. I have put 2 1/2pints back in the ****** but have not filled the rear yet, so now would be an ideal time to count the ring gear teeth!I also purchased magnetic plugs for both drain and fill for ****** and rear. They wre cheap enough and I figured that fluid is so thick the chips will float rather than sink to the bottom, cheap insurance even if I am wrong! The level is confusing because I have read everything from and inch below the fill to all the way up until it runs out of the hole. i will probably compromise and go 1/2 inch below. The owners manual says capacity 2 1/2 pints for both until it runs out of the fill
 
lets get back to the question do i need an oil filter my answer is hell yeh ive spent 45 years working on anything from a chain saw to a V16 mine truck and simply if you havent got a filter of some sort you've got no hope of catching any contaminant
