Well what era the symptoms? Does it just plain not go higher, start
sputtering, cough & wheeze...
If the engine has not been bored out much yet, you can still bore it out
rather than get a new block. I think the max is something like .40 over
(correct me if wrong). That will give you a minor disp increase and will be
cheaper than a new block. I know I would rather do that than find a new
block..
