No matter how many years you build these flatheads you find something different. I just stripped a 59ab engine today, it has an 8ba crank, 3-3/4, .030 under with 59 rods and copper floaters, it's been run hard and put away wet, every bearing has split in the middle like 2 floaters, the journals are .008 .009 out around. They must have pounder enough with those out around journals to split those floaters. Has others seen this? I'm sure some of you have. Walt

But it ran as quite as,but I bet it would not go far.

hey Walt, I have no idea what you are talking about but dad and i went to Caribou and got that '49 F1 yesterday. wicked nice original truck. i got the motor unstuck today but compression is not so good on a few cylinders. zero actually. probably some stuck valves. i'll let it set awhile more with mmo. i started the thread "A '49 pickup preservation" -Chris

I drag-raced a '41 Mercury powered "D/Altered" in the early '60's. The engine started making a bunch of racket, and when we took it apart, some of the floaters had split, just like you described. I don't remember if they all did, or what else was wrong with it, as a good-running replacement was $35 in those days.
