Rebuild Questions
I have pulled the motor out of my truck on the pretense that i would find alot wrong. First I was told that I might have a burnt valve but then i took the heads off and i didn't find one. now i was suggested that the pistions had a bad ring. I didn't find either. Now that i have the motor out and have no "visiable" problems. I might as well rebuild it. I was thinkink about the 400 Kit out of PAW. that would give me the right crank and all. i am thinkin about having the block machined . but from the above you can see i don't know alot. and i don't really want to listen to the folks around here. So...If i take the block and the heads down the the machine shop...what should i ask for?? how do i not look stupid i don't want to look like a girl going in there and not knowin my stuff. Thanks guys.

A good machine shop will check the block over, and tell YOU what you need. All you need to tell them is that you're rebuilding it.
Don't order the kit until you find out what they did. If they bored the cylinders, you'll need oversize pistons.
If you're getting a new crank, tell them so they won't turn down the old one.
Take the heads too, and have them rebuilt at the same time.

It is actually better to just come out and admit you are a neophyte and would appreciate any good advice. Don't be embarrased to say "I don't know!" Making sure you are dealing with a quality shop first is job one. If it is not a clean, well lit, orderly place, take your work somewhere else. Ask people you trust with whom they have had good dealings. The best shops I have used have been happy to spend some time to help educate me and I have rewarded them with loyal business. It is my opinion if the machine shop needs some parts, let them sell them to you, they are there to make a living. The boring process goes like this... shop measures bore now, calls out what overbore is required.... orders pistons, measures pistons, bores to size. GL
