Are you sure that's the stroke and where did you get your info from? In that range I've heard of 3.50, 3.510, 3.55 ( sbc rods) 3.58, and 3.59. If you want a billet 3.625 then you have several choices, on the shelf (Crower) TA Performance or a few weeks (12-16+) wait Bryant, SCAT, Moldex, King, and Winberg.
