Hi guys, I'm new here and starting to learn about flatheads.
Or more precisely, how to work on them.
I recently acquired a couple "late" V8s.
One a Ford and one Merc. According to the guy I got it from, his grandfather, uncle or whatever had a junkyard years ago. After the old man died they cleaned out the yard. But he saved this engine. It was in an old school bus.
Now the questions.
Would the bus have come with the Mercury engine or maybe replaced at some point. I know the school district garage would have done the cheapest thing to keep the busses running. Including getting a junkyard engine to replace a bad engine.
This engine is complete and original.
EAC on the heads. Big truck trans with a brake band around the output shaft or, I guess an E brake.
I know the Mercs had 4" stroke. (Referring to 49-53 engines only)
I read that all flathead rods are the same length.
Did the pistons have a different pin location?
Had to, right?
Would this be a truck engine? Or were they all the same?
It looks like "L1124:" cast on the back of the block.
Looks to be the same physical size as the Ford (C2002: on it)
I haven't tore into it yet. I'll do that this weekend.
A y info will be appreciated. Thanks.
