Farmall Repowered With Chevy Engine
“I bought a 1937 Farmall F-30 tractor minus the engine for $175 and then installed a Chevy 350 cu. in., V-8 engine that I had previously rebuilt. There were a lot of challenges in making this conversion,” says Glenn Buxengard, Spring Grove, Minn.

    The new engine has about 100 more hp than the original one. “The engine really gets hot,” says Buxengard.

    To fit the engine into the tractor frame, he had to discard the fuel pump and install an electric pump and a mini starter. He also bolted the Chevy clutch and bell housing to the Farmall transmission. “I cut a 1-in. thick donut out of some plate steel, welded the donut to the plate, and installed a sealed bearing. Then I hooked up an input shaft from a Chevy manual transmission and ran a short driveshaft to the Farmall transmission,” says Buxengard.

    The fan on the V-8 engine sat lower than the Farmall’s radiator and was therefore inadequate. “I tried using an electric fan to cool the radiator, but it didn’t have enough capacity. So I built a tower out of 1/4 by 1 1/2-in. strap iron and installed the Chevy fan with bearings, then ran a belt to the tractor’s crankshaft pulley,” says Buxengard.

    He couldn’t find a step-up transmission, so he made one using the input shaft above the tractor’s driveshaft, with no. 60 roller chain and sprockets running a shaft under the tractor that hooks up to the pto. “I leave the transmission in neutral and shift the pto in gear to put it in road gear. One time I revved it up to 3,000 rpm’s and went 30 mph, but I didn’t dare open up any farther,” says Buxengard.

    He installed chrome pipes on both sides of the tractor, fastening them to manifold headers that he turned upside down. “I bought the headers from a company that specializes in race cars. I had to turn the headers upside down so I could extend the pipes upward instead of down,” explains Buxengard. “I installed homemade baffles inside the pipes to reduce the noise level, but if I open the throttle up the engine still really makes a lot of noise.”
