I have recently purchased a 49 f-1 with a flathead V-8 and I was curious as to what I have. The markings on the heads read NL 132 on a small screw on plate below that in big bold letters is EAC then below that it says Mercury USA.
I know that this is the flathead forum but maybe you can help with the tranny too. It says T87D-1 and below that it says W.G. DIV then below that it says SB2
any help from you Ford officianados will be greatly appreciated!
Welcome and congrats on having one of the best V8's on the planet!
Your flathead is a '52 or '53 Merc according to the heads, but as all Ford/Merc flathead V8 stuff interchanges you won't know for sure until you dig deeper into the engine.
For the sake of argument the EAC would have the 4" stroke crank and HP was rated at 110. None of the other casting numbers mean anything at present - apparently local foundry ids.
Did they change the entire engine or just the block/heads? i.e. - does your carburator mount with 3 bolts (Ford intake) or 4 bolts (Merc intake)? You should be able to find on the rear passenger corner of the intake flat an alpha-numeric series stamped there that will tell you when your engine was assembled.
Tranny: I don't have any number refs close at hand, but you should have one of 3 that Ford used in '49.
Standard equip - Light duty 3 spd, all synchro (looks like car tranny - narrow gear box.
Optional equip - Heavy duty 3 spd, synchro 2/3 spur 1/R much larger case. OR a 4 spd, all spur gears.
