OVERBORE ADVICE ...please help

[tristan rizzi]

HELP
Can someone please tell me if a GEN I cyclinder liner is capable of supporting a .030 overbore??? Will the wall be too thin?? If this is the case what is the maximum that it can support. Secondly if it can support the overbore what are the best pistons for the job??
Thanks Tristan

Try taking a look at this from the other end. Find the piston you want to use and verify it will come in the size you need. If your block will clean at .020 then take a look at that. I don't think .030 is any concern however, double check my advice. If you are going for pistons, lighter is good, but not too light, shortens the engine life, also keep the ring lands as close to the top as possible. Reasons if you need em.

<HR></BLOCKQUOTE>Bob,
I was just curious why it would be good to keep the piston ring land close to the top of the piston? I thought it was better to keep it lower.

Your advice is appreciated,
Chuck

Thanks for the help.
I will definately keep the boring to only what is required.
