You can not bore your own engine. It must be done at a machine shop. An easy way to find one is to just look in the yellow pages under engine machine shop.

What is it you ask:

Basically metal is removed from the cylinder walls (where the piston goes up and down) of the block. This can be done for two reasons: 1) to remove scoreing (scratches) or 2) to increase engine displacement (make it go faster)

This is a very basic explaination. Hopefully it should help you ask follow up questions if you do not understand.

Very nice car by the way. You getting ready to restore her?

actually i think resotring her would cost more then adding a couple hundred horses to her. Im thinking about just taking her to the local track or something like that. The transmission isnt orginal the last owner replaced it same with about everything but the engine. Supsension redone everything is basically redone except interior, body, carb, and engine. what size bore do you recommend?

Normally an engine is bored between .010" - .030" (thats 10 - 30 thousandths of an inch) basically 1/64" - 1/32" less than 1mm.

Do not take this the wrong way, but I would not recomend any engine modifications at this time. Drive the car the way it is, find out all of its good and bad points. Fix all of the mechanical, especially the brakes. Then when all is well, then work on modifying the engine, by then you will have much more knowledge of the car and know the questions you need to ask.

Also adding a "couple hundred" HP is not cheap.

You may want to read some of this post

Don't get ahead of yourself, take time to smell the roses, enjoy this hobby. It would be a shame to see a beautiful car like this wraped around a tree because you had a 500HP motor and no brakes.

LOL I thought about that too after I wrote it. But I figured anyone that asked what is boreing an engine could not do it himself.

Actually you don't need a machine shop, but it's a fairly cheap thing to have done by a shop.

Almost anyone could bore their own engine. Most people are boring enough.
