The V8 conversion was produced by Funk Aviation, many of the conversions were installed by Ford dealers on new tractors. Funk also had a straight 6 conversion for the 8N that produced 95 horsepower. I guess there primary use was to get more power, as the original 4 cyl had 28 horsepower I believe. I saw an ad for the Funk conversion in the YT-mag site it talked about making the 8N V8 a 6 plow tractor I think, it would be a really bad hombre if it had more weight. The local tractor pulling accociation made the V8 8N illegal because they said it wasn't "original" but I think it should be legal because so many were installed by Ford. But these must be the same type of people who don't count the Clinton affair as "intimate contact". These kits are still being made I've heard by a different company but I don't know who it is. Hope I've helped you the best I can.
In scrolling thru some of the photo collections on the net I have come across several 8N's with a V8 engine. They have twin stacks and I read where they developed 100 horsepower. Are these modern modifications? and if not, what did Ford intend their primary use to be? How much fuel did they burn? and even with the 100 HP, without the weight-to-power ratio being higher, what could they pull? Just a few questions that I know you fellers know the answers to.
