I had originally thought of putting this '37 UL motor together as a Flathead, but as I started searching for missing parts, iron heads, connecting rods, & flywheels I kept looking at posts about the Flathead top ends lasting only 10,000 miles. I looked at a Panead cylinder that I had sitting on the workbench...It drops right on the UL cases! I have a set of Panheads that are drilled for outside oilers sitting in a box. If I went in this direction, I could use standard overhead HD connecting rods and early overhead flywheels that I also have. It looks like I could get a line connectd to the sending unit hole for the oil pump and use that to feed the heads.
I was thinking that I could modify the lifter blocks like a 45 Magnum and use Sportster camshafts.
Does anyone see any drawbacks to this setup?
