two different problems with a stroker engine on a hs-50 . one side of the rod will hit the side of block(front) and the other side will hit the cam shaft between the lobes. wait three problems? if you use a h50 crank? the counter weights will hit the lower cylinder. wait again, fourth problem?
counter weights will hit the cam lobes:doah:
i think by now your really start to hate me for posting any of the information above
but you did say something that just might work?
you said you could make a billet rod.............yes:thumbsup:
if a guy could make his own billet rod in any length/dem#
i would go with a 2.815x640x.490 wiseco piston or maybe little bigger if bore size will allow it?
then take the stock hs-50 crankshaft and have it ground down .875 with the off set. making your self a poor mans stroker engine. i don't see you having any problems making the crankshaft weak at all. not with 7 or 8hp+ or maybe little more.
if you can do all that? then making a billet flywheel for it would be real easy.
purchase a animal adjustable flywheel that as the center adjustable hub. take it off and make a new hub for you tapper shaft...
this is all base on using electronic ignition(coil on the outside of the flywheel)
there is more things you could do to it. if you really want the motor to spin.......
