I'd vote holes, because that's what all the big piston makers do and there must be a reason.

 

I vote crx.

Seriously, holes. Path of least resistance.

 

I VOTE LOG!!!! Holes that way there is more material to support the oil contol ring.

 

lots of people like holes, but everyone likes *****

 

HUH?

 

Holes soundmore Logical but what will happen if i use the Piston with the Grooves? How with this effect my piston cooling? I have Oil Squirters inside my engine.. So if i had to run Groove pistons will my Oil Squirters will be wasted?

 

Ambivalent.

 

holes, grooves, what ever I can put my ***** into.

my dad's friend has raced cars and built engines for a very long time (with very good results), and he is quite set on holes.

 

ambi what?

How can i get a answer two my question? otherwise i will be spending alot of time and money building a time bomb...
