The early 41 Mercury radiator may have had the split but the late ones did not.

I put all 6 volt LED bulbs in my 41 Mercury. Only thing to remember is if you have turn signals on your car and you change everything to LED then you have to change you flasher to LED also.

Re: Trying to figure this one out…. My dad put all the gears out of a 40-48 transmission into his 37 case and it worked great.

There should not be a jumper wire. You are correct. The thicker yellow wire is the power wire. The other wire is from the horn button and acts as a ground to the relay. The whole unit gets a ground thru the fender. I just restored my horn assy. if you have any other questions.

If you give me you email I will email some of what I have. Feb-26-41 High compression cylinder heads installed. Service Letter 148 "On future 95 H.P. engines through production, passenger car motors, as well as commercial, 3/4 and one-ton engines, will have 81A-6049-A and 81A-6050-A cylinder...

That is the way these left the factory. Verified from the original owners they they have never been changed. I have an original service bulletin book from 1941 that states that the 41 used 81A heads.

The V8 Times is not correct. 81T heads were used on 39 and early 40 Mercurys them they whiched to 81A heads through 41 Mercurys. I verified that by original notice letters from Ford and by checking several all original 41 Mercurys (early and late) with less than 30K miles on them. They are also...

That is correct for earlier 40 Mercury.

I have the original Ford letters that said they changed to 81A heads during the 40 model year. I have confirmed that by looking at several all original 41 Mercurys with less than 30K miles on them. Both very early and late models.

The 39 and early 40 Mercurys used 81T heads off of the trucks then switched to 81A heads during the 40 model year to increase the compression.

I went online and bought LED bulbs to put in mine so they are brighter. You can buy them in 6 volt or 12 volt. They are brighter and use less power. Just remember if you have added turn signals that you need to change you flasher to an LED flasher. I have changed all my bulbs to LED.

The 41 Merc had an early and late radiator with the later having a larger upper tank.

The blocks with the flat milled intake manifold surface add 99 stamped on top is a 39/40 Mercury engine. The 41 Merc engine had the pencil shelve above the timing cover and raised deck intake manifold surface. 41 Merc engines were still painted green not blue until 42. This has been verified by...

The 37-41 distributor was the same. The 42 had the crab distributor. The end of the cam was flush with the timing gear. Did the 42 have the recessed end on the cam or did they not change that until 46?

I have been told that the 41 and 42 Mercury used the same block but not sure.
