no your not a smartass, this crank assemble is complete from eagle 410cid/360 sb dodge, the 2050gram bob weight is from eagle, the rod / piston weight we done with a digital scale and a gig to hang the rod parrel to the scale to get a true reading, if the scale is reading right? the only shop that balance cranks is in the next province 1600km away, after ordering the kit from summit they said it was internally balanced but when eagle was contact they said that final balance should be checked. i understand the 100% of big end + 50% of the small end/piston/ pin/locks/ rings then x2 for both assembles but even these number seem way of for a complete kit that was order. if we had known that eagle would have checked that final balance for 200$ we would have done it but thats to late now. it cost 150$ just to ship it to armstrongs in N.S.
