I have the OHIO crank-4.75 (8 Bolt ONLY)and have a reg cam location Indy Maxx block..First of all the Crank was spot on..everything checked out fine..i also had them cut .180 off the OD of the counter weights when i purchased it.. it is a chevy rod journel..(2.20) there was a small amount to be clearanced off the rod shoulder,mainly the rod bolt.. i have about .100 of clearance between the rod shoulder and the cam..what i did to help with clearance was to stay smaller on the cam profile and stepped up on the rocker ratio..but donr get me wrong..i do have room to grow and if needed later i will clearance again since i really didnt take that much off of them..i will post pics of what i did..my cam profile with the 1.5 was .700/.715 roller now with the 1.6 rockers i am .747/.765 and that is plenty to make my heads flow and i still have .100 clearance...my block was clearanced for a 5" stroke but dont hink i will ever need it...
