my stepdad bought a 76 440 trail in mint cond for $ 950 all original cond. the guy bought it from a neighbor then decided he didnt want it anymore. the 440 are not that hard to find, and repo hoods and decals are fairly inexpensive. i just dont understand why some people think there sleds are worth ...

the service manual from merc says 21 degress @ 3000rpm. cant help with the wiring diagram.

buck, the snowtwister parts manual stats the bore on a 644cc is 3.125 or 79.38mm and the stroke is 2.56 or 65.02mm.

some joker on flebay seems to think his 440 trailtwister is worth $3300. maybe he thinks its a liguid merc. that sled is worth $1000-$1200 tops. good luck to him. wait i think i see gold colored sparkplugs, well then maybe it is worth $3300.

D A Z a 1975 merc would be the free-air. from what i seen in the past, a used-condition freeair 440 would bring about $1200. now ad to that a new hood and bellypan and decals a new seat cover, you would be around $1800 to $2000. so i would say for a mint 440 merc would be around $2000 to $2200, mayb...

merc-eric I believe he is getting $120 to $140 for the one piece bellypan. also were the spindle stubs go through the bellypan are marked so you now were to drill the holes, same for the hood mnts
