It depends on how much time, effort AND money you want to invest. I have a 44 B, and let's face it, while stock, they are really weak. I bought it last year, pulled it once just for fun, and it did horrible. The 1996 Two Cylinder Mag. (July/August) featured the early styled B. On page 2, they said the HP was increased to a whoppin' 11 HP on the drawbar. In 3500 lb class, you are really in trouble. This early Spring I took out everything up to the crank: then pondered, should I just bore it out, put new rings and pistons in, or keep going and stroke the crank, and everything that goes along with it. Soo, I went ahead, and pulled out the crank (not as easy as it looks), and sent my crank, rods, and cam to Schooler Motorsports. They stroked the crank, lengthened the rods, and exchanged my mild cam for a pulling cam. They conveniently had a late model B block and short pistons and rings already there. Presently, it is punched out to 4 7/8 bore x 7.25 stroke.....increased volume and compression too. Now I can easily pull 3500 in 2nd gear, up to 5000 lbs (1st gear of course). It is a "bear" to start(hand start), but now l don't worry about running out of power. I'm very pleased with it's performance. The way I look at it, the internal work is all done. I was thinking, what if I didn't go to this extreme? Would I regret only going part way? Try explaining that to your wife; "Dear, I'll have to overhaul the tractor again, it doesn't quite have enough." My wife would go ballistic. You other pullers know I'm talking about. Well, just my thought's..... a matter of preference. Good Luck
