Johnson 3.5 bore limits.

[James R]

I am looking at buying a used 150 block that the seller says has been honed and is standard. Can anyone tell me what the bore limits are.
Thanks.

I have a manual for a 60 degree looper motor of the 90's...through and past 2000... the bore was 3.6"....specifically 3.5995-3.6005".......if your bore is 3.500" you might be taking about a pre1991 block
