I thought that before I posted, but figured they wouldnt be powerful enough. I did find something though. It cost $130 for the starter, but then I noticed they had a part listing. $45 for just the motor - score! Its the biggest thing they offer and I think it will fit out needs nicely. It provides 37in/lbs (I was exxagerating on the 50 part - we absolutely needed 35) at enough RPM to get some more mechanical advantage out of it just for more breathing room.
I called them up (tower hobbies), and gave me the weight (its for a supermilage car) and even a dyno sheet. We saved over 15lbs from our previous starter. Its a Sullivan Stage 4 motor if that means anything to anyone.
