a9sec70cuda runs a 4.500*4.500 Hemi (I think) in his NA 9.50's ....

Here is mine (race Version) 4.500 and will be NA until I have the guts to start throwing some N2O at it ... I noticed in my andyf book about the world blocks the street version are not tapped to run the powerglide or have the extra ribbing across the valley and the lifter bore's are not bushed like mine(race version) does.... Which also andy notes are more exspensive in his book.
