I'm building a 1948 F1 truck. The flathead in it know is no good. I "Finally" came across a good flathead motor. best I can tell it is a 1953 truck flatead. One thing that has me puzzled is the water pumps on each motor. On my 48 the water pump is part of the motor mount. This motor I have now it has a plate that bolts to the front of the block and comes down under the crank shaft pulley with a single hole in it. I guess this is the motor mount of this motor or what ever it came out of. And the water pumps are different to. The one's on my new motor the sides are at a angle. My question is can I change out the water pumps so I can mount the motor like it is suppose to be mounted in my 48 F1. Everthing eles looks the same on them. I can give you all some numbers off of it tomorrow if this would help. The motor in my truck know says ford on the head and 8BA. The numbers on the heads on the new motor start with ECM and then a long number. Plus the oil pan is different to. My old motor as a big looking oil plug in the middle of the oil pan and is fairly straight. The new motor has the oil plug or bolt in the back of the oil pan but it is on the bottom of the oil pan and it has 3 off sets in it to. Can anyone let me know if I can change the water pumps out and use this motor in my 48 F1. "ANY" Advice at all would be a big help to me. I'm pretty new when it comes to flathead motor's. Thanks Scott
yes you can put your 48 pumps on the other motor I did the same thing take off the bracket under the crank pulley cus you don,t need it
don,t forget the bolt inside the rad hose fitting to get your pumps off
if you need more help let me know
Scott, you can go ahead and change the oil pan, the oil pump pickup and the water pumps. The blocks are all the same. Only differences are the bolt on accessories.
In '53 the trucks used a center motor mount and two mounts on the bellhousing. That's why you found a plate on the center of the engine. You can pull it off and replace the car pumps with the truck pumps off your old engine.
Numbers on the heads only means right and left and which year upgrade it includes. Not to worry about them. You'll find 8BA and EAB prefixes for ford heads and 8CM and EAC for merc heads. next numbers for both are 6049 and 6050 perhaps followed by a letter or two for improvements.
Thanks alot to both you guys. I know I will need more info from you guys about my motor. I have another question for you. If you are standing in front of the motor on the right side where the intake manifold is stamped in the block is the number (F98992) and beside of that is the number 21 with a circle around it. And on the front of the motor when I took the intake off there was another number and it is (017160) And on the back of the block there is a number (E 804) Do these numbers mean anything. I was told the number on top of the block (F98992) is the number to look up. I can't find any of these number's anywhere on the net. Am I chasing a ghost or do they mean something. Sorry if I sound dumb but I'm learning about these motors. So I'm trying to find out everything I can. Again thanks for the info on the motor mounts and the water pumps. I'm sure I'll have some more questions very soon. Thanks Scott
None of those numbers sound familiar to anything that will help you. On the intake flat you'll typically find a bunch of numbers that are proof or inspection numbers. Only person they meant anything to is the guy who stamped them.
Only on the rear, passenger corner of the intake flat will you find an assembly date code. Letter/number(s)/letter. Check out Jim Marlett's website for more info
Thanks mtflat. I found that number on my block and went to the site you gave me. The number is (C 9 M) So my motor was made in May 9, 1950. So I have a 50 model block instead of a 53. It just has 53 stuff on it right. Thanks for the help and the site. Talk to you later!! Thanks Scott
