got a guy in our pulling club that has a ca allis chalmers (i think thats what it is) he pulls in our club once in a while and then a few other places in the farm stock classes, its no big monster stroker tractor but he says hes got alot of power and how he whooped up on all these 60 horse farmall M's last year.. he says hes boring the motor out with 4 and 1/8 pistons and stroking the motor like a half an inch or something like that and its going to be 201 cubic inches and hes using d-19 rods and has the head somewhat ported and polished and he says hes going to have around 100 horse and still pull in the stock class with his 14.9x24 tires non cuts, my question is a 100 horse even possible out of a set up like this? he thinks hes gonna whoop up on my M this year but im going to run a c281 with high comresion pistons,450 cam, brand new 450 lp head, stieners new lp manifold, stock stroke,electronic ignition, like 10 % over stock rpms ,and 14.9x38 tires.. does he have a chance or is he dreaming ?
