Piston grading

[John Robinson]

Who`s doing it & who`s not. For those who do not grade their pistons, have you ever had a related problem? It is very time consuming but I do it anyway. I would love to have a good excuse to quit though.

Can you walk me thru the process of you grading your pistons...

I know it has to do with protrusion from the deck, but how do you determine what you need before you buy pistons? Are all the holes the same or can they require different grades?

I've always just bought A. No problems, but I'm sure there's someone out there who will say I'm wrong.

When in doubt, get "A" grade pistons!!!

My pistons are probably d rated cause that's how my motor performs on the dyno. LOL
