Another good combination for you SBF guys to consider is the Boss 302 block that Ford SVT released a year or so back, with a set of either the 4V Cleveland heads, or the Aussie Clevland head.... Put in a light crank, aluminum rods, light pistons, roller cam and rockers---- Then go hunt down the mouse motor chebbie guys and show them what a high rpm engine REALLY pulls like........ That poor sbc has never seen a head that will flow like that Cleveland 4V that's been tweaked!!!!!!

PS-- Before you sbc guys unload on me with a bunch of "virtual engines" with "virtual performance", I am ready, willing, and able to put one of these together and back it up with a sizeable wager......
