Yea I couldn't swing the cash for aluminum. So got the iron. Plus I'm running iron heads. Either way you sure can't go wrong with them. They are real nice blocks. I'm shooting to have it in the car by summer so....fingers crossed. If I see any fall off the back of the delivery truck I'll send them your way. One funny thing...when Fed-Ex freight delivered the Genesis block from KCR it was in a Shelby aluminum block box. I figuered they just re used the Shelby box to pack mine is...as they did. But I would have gladly taken the Shelby block if there were a mix-up tho... Oh well....
