That's a slant 6 not a flathead.

I daily drive a 51 Plymouth, pretty much stock. Yes, they are that slow. It'll do 70, but I don't like pushing it that hard.

97 hp, 3.91 rear gears, three on the tree. P255/50R17's in the back. About 3400 rpm at 70, Those old flatheads have a long stroke and massive pistons so high rpm is not a good thing for them.
