Default Oil pressure on my 50 Ford

When I got my 50 Ford it had a modern oil pressure switch which showed full pressure all the time and I knew that was incorrect. I got a correct oil pressure switch and installed it.Big difference in oil pressure.About 10 pounds at idle and almost 30 pounds when driving down the road.Wish it was more it a bit scary.My 33 is like that and at idle not much oil pressure but driving down the road the pressure goes up a bit more.Are most flatheads like that?I got to road test the 50 yesterday and sure did enjoy that.It had not been started since Oct. A little over 5 months I guess. Had to prime it with a shot of gas and it fired right up. I got a electric fuel pump to install for a backup. I know some of you don't like that but I have it for a backup I do tour a lot.I sure am looking forward to summer.Any of you out yesterday for a roadtest? Sure hope so.

Hi Ken, it was a nice cay here in Mississippi yesterday, too. A 76 degree, sunny day felt good after the unusually cold spell we've had. I didn't get the old car out but will before the week-end is over.

I don't think flatty's were ever noted for their high oil presssure. Your's sounds good. Nothing to worry about, IMO.

10 pounds at idle? Sounds good to me.

Redneck, I had my '50 out this morning for a while. I now have over 80 miles on my engine rebuild and all is OK.

The 50 coupe in my picture is an original (other than wheels & tires) with 15,000 miles. It runs about 35 lbs. at speed and 15 lbs. at idle so your pressures sound good to me. I once drove a 36 that had 15 lbs at speed and about 2 lbs at idle. It scared the heck out of me but it never let me down. Our first run, here in the Pacific Northwest, is tomorrow and it's actually supposed to be sunny.

ford says #30 at 30mph, if you have any oil pressure at idle your lucky, ford doesnt even give a number for oil pressure at idle, your good to go, so just drive and enjoy it

My '50, that lost a piston in Oct in KS., ran before and after the rebuild at the pressure of Rednecks, and it showed no visible wear on the main bearings with 82000 miles and minimal on the rods, It is back together with the original standard crank , so I guess we can be comfortable with 30# pressure.

I had a '46 pickup with a 59AB that showed 0 pounds of pressure at idle, but ran great. Sold the truck and it's still going today.
