How do I know when Its time to retire the block?


Any qualified machine shop can tell you that.. Typically when you go over 93.5mm or .060, it's time to be concerned - not all blocks can be overbored beyond that.

I agree with the above - talk to engnbldr.. His shop may even do complete longblocks.

If you want more than 140 or 150 hp, look to DOA or LC.. Just understand what you're buying.
