Looks like you have two separate 4 cylinder engines sharing a single crankshaft. Cooling & fuel systems are separated & looks like maybe the firing order alternates between sides. That is one of the later flatheads from about '49 - '53.
My first flathead experience was when I was 14-15 yrs old. My buddy bought a '38 Buick and the guy he bought it from said it needed rod bearings. We go to the auto parts store and guy says we should buy bearings .010 over. So we think what the heck if .010 is good we'll go .020. The Buick was a straight 8 and we didn't know enough to cut the crank to except the new bearings.
I've only had 2 FlatHeads in my life.
First was a Harley Davidson 1945 '45 Solo - No miss on that one
I finally added a seat on the back fender and the bike was immediately stolen
Second was a '63 Rambler American 220 station wagon with a Straight 6. That *car* was a real hoot.
Every time the head came off it had to be shaved.
At the end of it's life it would only run on premium gas, which was like $.30 a gallon at the time...
The Rambler was THEE easiest car to work on that I've ever owned. It was like they knew you were going to be spending a lot of time under the hood
Like a Jeep - The engine could be rebuilt while on the chassis.
Good old American Motors......
Howdy DeadEye,
I had a '62 Rambler station wagon with the 6 banger also,but
if my memory is correct mine was a 'Classic". The seats were great
at the drive-ins.
