does anyone know anything about them? they seem pretty decent,but i really dont know the difference,between casting,and nodular iron. i was going to go with either this one,or a eagle/scat from summit. there all about the same price. around 230 ish. or does anyone else have something else i should consider? thanks alot.

p.s. the car will be mostly a street car.thanks again.

also what cam would be considered a good cam for my setup? i would like some lump in it,but i dont want it to be real extreme. i plan on running a supercharger/turbo as well.and it will be a man. trans car.thanks alot
