    I've been scouring the boards for some info on these, thinking of using them in my fairly mild street/strip 455 build.
    Is pin height 1.997? If so, that is a very nice change for quench.
    What cc is the dish on the "10:1" pistons? This I haven't been able to find any definitive answer on, and would like to do some compression calculations to see if they'll get me where I want to be.
    Lastly, I know a lot of the time it is recommended to upgrade to forged pistons. This engine will be all iron, small valve, figure MAYBE 425-450 hp range, and I can't see a need to spin it more than 5500 rpm, mostly just street driving anyways. Are these a suitable piston for that kind of work, or is it really time to go forged? I will have arp rod bolts installed, rods resized, and the rotating assembly balanced either way.

    1.990" compression height, 23cc dish. They should be fine for your application.

    Looks like I'll be mic'ing the bores, and probably making a phone call today. Thank you!
