I believe they are the same. I think the only difference is the camshafts and starters.

Plus the timing chain vs timing gear set-up.

Which one was rebuilt and spun a bearing, the counter rotator? Any indication why it spun?

And you need to change the rod on the bearing that spun.

thanks guys -it was the reverse rotation engine and the cause was me. installed the engine-pulled out distibutor to prime the oil pump. put it back in and didn t tighten down the fork enough- while motor was running the distributor popped up a bit dissengaging the oil pump drive. doesn t take long to ruin with no oil pressure.
