Anything assoc. with Carrillo is expensive, usually great quality too, 
not sure if it's any higher quality in their piston line thou, 
maybe not another $500 worth over a Diamond piston, 
{the 14:1 could be a partial reason for extra $$$ they are a custom order} 
that use the same materials & same weights as CND'ed on a similar program

Diamond Racing Pistons 
Some usually come with pin & locks at no extra charge,
that might be a reason the are cheaper in cost, custom orders are more $$$ like always

I have used Carrillo Rods occasionally, but never their CP brand pistons, 
I was partial to JP1, Venolia's or Child & Albert's pistons, rods &rings & bearings, 
back in the day, I had to drive down to Long Beach to get them, say hi at-least
Thanks Uncle Joe {Pisano} 
may he rest in peace 
he gave them to me "usually" if he had them on the shelf 
{he's not my real uncle, just a great family friend},  
but if they were a custom ordered, rarely did I need them custom spec.s,
that if he didn't have stocked already, 
then I'd pay production costs about 60% of jobber/retail was about $100 a hole/slug 
without his great help/support, 
I 
wouldn't have been able to race anywhere near as much as I did back then...
not sure who even owns/runs Venolia or Child & Albert's now, 
I haven't dealt with them in years now...
