44 massey performance options

[Anonymous-0]

Hello all,
i am looking for ideas on some performance enhancements on a 44. i have a friend who pulls my old stock 44 since i have moved on to a different tractor. Well instead of letting my 44 set he pulls it. Anyways we have an extra motor and want to do some minor modifications. My questions whats the best bang for the buck. He does not want nothing radical. We were thinking of bigger bore and automotive style pistons but are not for sure. So if there is any combination of longer rods and different pistons to raise compression. Also is there a better or propane head. Basically if there is any common combinations to get around 350 cubic inch or possibley more i would appreciate some advice. Thanks in advance.

Get a bore kit for a 44 Special. Stock 44"s have a 260 engine, this will take it to a 270. I would also shave the head and have a three angle valve job.

You might want to get a stroker crank (some times on ebay), but this may be more than you want to do.

M & W made a 4 1/16 bore dome piston kit for the 44, it will get it up to 285 cu in, if my memory is correct. My little brother has one in his 44. The dome on the piston is between 3/8 and 1/2 tall. That bumps the cranking compression from approx 120 psi to 185 psi. The kit dosen't require you to bore the block. Any bigger than 4 1/16 bore and the bottoms of the sleeves get too thin and break, unless you bore the block itself and fit custom sleeves and pistons. As for the lp head I was told they are the same casting number, but the parts book does show two different part numbers because the lp head was fitted with exhaust seats that would be compatible with the lp fuel. Cheap and easy way is to use the m&w kit if you can find one. Other than that custom made parts are the only other option I know of.

Hope this helps,
Kyle

549 int truck pistons and custom sleeves will give you 350 cubes same pin size 4.5 inch pistons you have to bore the block for the sleeves
