I got a question. I have all ways been told that to get more horsepower you need more cold dense air and more fuel. On the farmall H & M the manifold serves booth as the intake and exhaust. The air is drawn into the cylinders through the carb and past the hot manifold creating hot air. Is it possible to run like headers on them for the exhaust maybe pick up coupple of horespower, replace the oil bath cleaner with K&N filter??

The Denny header dont work well in low rpm engines, they may help a 3500+rpm engine breathe more, but they usually screw up a stock engine. Just too much manifold for the cubic inch. Most, just cut the casting away from the intake and lose heat, thats about the most cost effective way to do it, if your good with a hand grinder, wont take long to remove that iron. if the carb cfms are set up correctly, that air naturally cools thru the venturi. Most of them that sweat around the carb flanges on a 90 degree day are very close to being right. You can run a cooler burning fuel, like Ethanol to help cool the mixture down, and run a long air cleaner tube with the filter on the end to the carb inlet. that will help keep air cooler. visit www.thetractorshop.com for more information. or email me.

what other dodads could I add to get the most of my tractor foe pulling. I've been told the K&N filter is the best horespoer gin over the stock oil bath.

Get a LP. intake and exhaust manifold, or get hold of Hank Steel in Mich. Its legal to run these set-ups in most pulls headers are a no-no.

What kind of power do the seperate manifolds make ? A couple HP would be a 7-10% increase depending on where you start.
