there about a grand. Dont see anything special about them

i didnt see anything that special about it either?

Its only redeeming quality is its made out of billet aluminum. Its not even that trick for that kind of money it should have at least an aluminum sleeve, be polished and have heavy duty studs for starters. I highly doubt the motor runs cooler with it.

I would much rather see someone make an aftermarket head. That would find a way to improve performance over a ported stocker.

First of all it comes with heavy duty ARP studs. Also it comes with bigger fins. You can get it to be a 440,, 450 or 465. It also comes with the piston and gaskets. For just $950 I think it is worth it.

that is a killer setup, I have seen it. It has heavy duty studs and comes with a custom je piston to match. If mine ever blows up, that'll be the replacement.

i just cant see spending almost a grand on a cylinder that has no major effect on the performance of the motor, Fulk is right, an aftermarket head is the key

i looked up some more info on it. Itd not billet its cast. But still a better quality casting than stock. You can make a stock cylinder do the same thing for 4 or 5 hundred less.

Though the duncan cylinder would look cooler.
