Do I need to bore over 30 to put in pistons?

The only reason to bore an engine IMHO is to establish the correct piston/bore clearance and ensure a square bore (i.e., no taper). The CID increase on a stock block (not the aftermarket ones that you can bore out huge) is minimal. If you can buy a piston and establish a reasonable clearance, square bore and the right surface with a hone, go for it.

Was I being serious ....

esll.


I've done rebuilds On very expensive # correct engines and the school of thought that I come from is to error is human .... when there is NO' second chance I have always have chosen to error on the side of caution. Old habbits are hard to break. Yet to blow something up or have something that does not work right when it's finished ..... at this point one should not be scratching their head .... what the heck went wrong??? Know what I mean!
