the motor for my sy is a 4-bolted balance shaft block...the cam and timing set are expensive...there's not a double roller set available for them but there is a single cloyes true roller...that alone cost me 150.00 and the cam is different so one would have to be custom ground... everything else was the same...shouldn't be any weaker...the bottom end is the same as a regular block, and thats where you need the strength IMO...
i was under the impression that the 96+ blocks had differences other than the shaft....i guess not...
