Ken , the Finnish Flash ( MAFO on the forum ) is awful quick with his " street " car. Technology with these things seems to go in spurts , but with the advent of the new Hemi's , I am afraid that any new " latest and greatest " tricks are gonna be one offs by individual builders / racers. The availability of blocks , head castings , cam cores etc. seems to be finite .......... though blocks have gotten a small dose of good news recently. But we seem to be the red headed step children of the performance world.
