sounded good
so does his scenario work or not
and why would he say use the 218 rods out of the short block maybe he meant 218 rods out of the lg bl.
how bout the 283 scenario
Tim, many years ago I wanted to build a warmed up 265 and did some catalogue research. If you use the 265 crank and the 236 rods, the piston from the 241 V8, either Hemi or Poly, should bring you out at the same deck height. The V8 piston will be a 3 ring piston of somewhat more modern design ('54 vs mid '30s), the wrist pin is the same size and fit, and the compression height compensates for the longer rod of the 236. All stock parts and the pistons may be available in various oversizes. Substitute '55 Plymouth 259 pistons and bore to suit and you have a 283" flathead six. If your block is sound enough, you might try to go out to 3 5/8" and use the '55 Dodge 270 pistons, but then you may get into the head gasket failure somewhat common to overbored 230s. My $.02 worth, although with inflation, it's probably about $.27 by now! Hope this is helpful.
Pictured below is a 283 CI flathead six as you described. I listened to this engine running on my last visit to the George Asche stable and it was very impressive. If I had the funding I would go this route.
Note the interesting thermostat by pass plumbing and the carburetor linkage. I do not know what carburetors are employed here.
