Andrews 37 is a great camset, alot of the time I wish I would have left my heads alone and used 37's and been done with it.You could have got by for much less money and equal or better performance by installing an Andrews 37 straight up. Too many good bolt in cam grinds out there to have to spend double for the cams and then buy an advance gear as well.
While your at you might as well go to 95", 96" or 98". Just a little more time and $ while your there.Am thinking of putting Andrews 37's in my Bob this winter. It's a stock 88. What difference will this make for my bike?
