Wat can be done to a l28e block at a maching shop with out making any part
bigger or boring anything out cleaning , port and polishing , :104:

hone the cylinder walls, steam clean the block or something like that

coudlnt u be able to take off the manafold and enlarge the ports ? its just a thought..

now that I read the original question... it doesn't make much sense. Sounds like you want to know what to do without porting anything... sort of... porting and polishing is never done on a block anyway.

We are talking about just the bottom end... the BLOCK, right?
without boring it, all you can do is clean the block and hone the cylinder walls. Then re-ring the pistons later.

wat the maching shop could do to any part of my engine.

So call up a local machine shop & ask them what is involved w/ a "clean up" or "rebuild" of a block.

you want it taken apart and cleaned up and put back together? thats all?

yes. but i want to know wat they can do to incase they offer it to me

This thread is giving me a head ache.

There is one small problem with your request. Sometimes things HAVE to be enlarged due to wear or damage. If a crank journal has excessive taper then it will have to be ground down to compensate. At which point you'd need a thicker bearing. If your cylinder walls are scuffed or scratched then they would HAVE to be bored over. How much would depend on the extent of the damage.

The only way you'll be able to get away with not oversizing anything is if the block is in perfect condition. Now there is a very good chance that it is so dont fret too bad over that.

So what you need to do is call up the machine shop, or even better go down there so you can check out the facility, and talk to they guy. Tell him what you're looking to have done and ask him if has any suggestions and have him explain all his suggestions so you know why he's suggesting it. They wont be able to tell the extent of the work you need done until they see your block/head. If you want the bare minimum done then tell them you just want the block cleaned up and checked for wear. If there's excessive wear then you're going to have to have machining done.
