Finished up the Chevy 4.3 in my 1941 ford 9n tractor

 

I love it!! Super-cool!! Good job!!

Reminds me of a neighbor's hot rod tractor when I was kid growing up in Iowa. His son (apparently a budding hot rodder) put an old 348 Chevy in a little bigger tractor and actually used to mow his brush with it (I distinctly remember the odd shape of the 348 chrome valve covers). The time was the beginning of hot rod tractors! In those days (1960's) for county fair tractor pulls you stepped onto the sled as tractors passed by to add the weight. They would give you your gate fee back and free pop (sodas for some of you). But when the hot rod tractors (and eventually super stock diesels) came into being and it became too dangerous with the sled being pulled much faster. You really had to be on the ball when the hot rods pulled if you was adding your own weight to the sled. Now look at them!

I'm curious what you had to do to mate the engine to what seems to be the original trans.

That would make a VERY cool parade vehicle to pull a wagon or something. Only thing I would change is to pretty up the headers. There is a process called electroless nickel plating (not chrome plating) that would work perfectly, but for best appearance I would do it on newly sandblasted headers. If headers are new and inside is also clean, it plates both inside and outside with a super-durable rustproof coating. Here's the finish you get. Not chrome, but a shiny matte.

That's pretty cool. We need more specifics. I need to make something like that for when the local farmers show off their restorations.
