No I am just thinking 557 then I was like whats 15 extra cubic inches. My Heads will perform just fine with a 572. Jut not high RPM's. Me and my dad are still mulling it over.

I was thinking a 4.3, for 547, but am considering a 4.150 for 528. I would love the 4.5, but with the heads we both run, I am afraid of lowering the torque range to low. Be sure and do some research on this, and let me know what you find out. I will be using Lem for my parts, and I will not be ready until after the first of the year.

Anyone reading this, we both run ported factory iron. (D0OE-R) This is due to rules.
