Is there a 30 over piston. I have already bored 20 over and I may need to go up one step. Price and Part numbers Please.

Some members have put in 40 over pistons, WHy do I need a new Block? Is 40 over too much to put in? I trust your judgement, but I only have 100,000 miles on this block.

The factory only recomends .050mm oversize [20 over usa]. With 30 and 40 over [using aftermarket pistons in US measurments] The cylinder wall is too thin to disperse heat properly.
