Re: L72 and L78 pistons

Not really needed...when I did a factory type build of our L72 it came in at a *whopping* 10.2:1 with all of the factory parts/pieces/specs.
Most of the guys I know are Pure Stock racers, so take this with a grain of salt, but they tend to want/need a more correct piston, ie, one that matches the actual published dome volume, not the TRW that is around 5-6cc short, yet is quite a bit heavier. And I'm guessing the majority of guys just let there engine builder supply the piston, and I have yet to meet one that will recommend the factory spec pistons unless it's mandated by class!
