Installing 1956 300 crop row engine into 1940 H

Posted by sandegj on September 27, 2012 at 03:16:53 from (69.19.14.34):

I need a little incite from someone that has more knowledge than what I have. I have owned my 1940 Farmall H since 1975 s/n 39402 and it always burned oil #2 cylinder. When I bought it, it wasn't running, I had to replace a broken hub clamp, replace the mag caps points condenser, then plug wires and spark plugs. Had to rebuild the carb just to drive it home. It had a rod knock so I slipped a set of rod bearings in it. Through the years I rebuilt the head #8043 with new valves, guides, and springs. Install a small diameter alternator what was used on Chrysler products and also used there solid state regulator. Later in time as the magneto got weak, I bought a distributor 90 degree angle, which was junk, so I took a 360 ci Chrysler distributor "no vacuum advance" and machined it to work then filed every other lobe off the reluctor and used every other terminal on the cap. I used a Mr Gasket spring kit using the light springs which brings the timing advance close to the production curve. I used the Chrysler E.C.U. also. Enough history. I want to put a 1956 crop row 300 engine s/n 57639 into the H chassis and found some differences. Mainly I bought a 1940 H distributor/ Mag drive and found the bolt pattern was smaller than what was used on the 300 front cover. So one of my questions is, can I put a "H" front cover and cover plate on this 300 engine ? Crank seal the same or different ? Pulley the same or different? What other differences will I stumble into. Thanks Jerry
