Hi Bill. I think there are a <span style="text-decoration: underline">lot</span> better (quality [img]<<GRAEMLIN_URL>>/cool.gif[/img] ) choices than those given. Plenty of those companies offer pistons designed for NHRA Stock Eliminator, which has some rather stringent &quot;stock&quot; specs. CP and possibly JE or Diamond come to mind immediately. I've spoken to CP at length regarding the possibility of using their Stocker pistons in a street driven car. Ditto with the possibility of using a modern ring configuration in a older engine. There's no reason (aside from $$$, which isn't outrageous) why it can't be done.
