the big mopar time machine is running backwards!!!next they will be recasting the 331-354 hemi heads and then an aluminum version of the poly heads.we are never going to see any good blocks thats a given.as we speak they are clearing out a spot for mopar in the smithsonian..but...we all have to applaud any efforts by manufactures to advance what we all know and love,mopar,even if its not a max effort gm killer product.this does show that there is a market for us,so maybe others will chime in with new and better products.until then,the big power boys will have to mill out a billet set of 5 in bore heads and build a block stretcher to use them.after all we been doing this kind of engineering for an eternity just to compete...
