low compression

The answer is stop being so thin skinned and do some research.:joker:

Edit - I mean you're off base to what is by definition a rebuild job. If you mean a re-ring or freshen up, then no valve job changes should be permitted. I thnk we need to call it a good running stock engine that is upgraded to whatever, with bolt on performance parts. That's really what you're talking about here and in the past, that's what I have built. I'd still take the 440 for the stroke, or 383 for the higher factory static and easier-to-deal-with smaller bore over the 400 but that's just me.

Hey Moper, firstthing I gotta say to you is;

Sorry. I came off F%^& up and cranky. No offense to you personnaly. My humble appologies.

Second, ya, lets start with a dead stock engine and leave the short block as deliever from the factory. Heads as well.

However I do understand that the heads may very well need to be rebuilt. IF one should want to do just the heads - with consideration that the short block is in good shape - then that would be fine to do.

Now if a short block needed to be rebuilt, then new higher compresion piston would be the right way to go about it. Not replacment slugs that allow an echo in the cylinder.
