I have three SBM 4.25 2" cranks on the shelf, 1 new 360 main, 1 new 340 and 1 used in good condition. I needing to build a very reliable (med rpm) hyd roller big inch road race track day motor. I want an Alum 360, Ritter is favoring/suggesting an Alum 340 for greater lower end block strength. Ritter alum block reported shortcomings have me stymied. What ever motor it is will get W8 Chapmans I have, the others will get my ported Indy 360's. Suggestions welcomed
