I also notice some of these smallblock strokers are bigblock (400 plus) cubes and are a lighter eng. So as Bill Jenkins proved when his lighter smallblock Vega ran right with the hemi's its all about HP to weight. I agree that alot of times the bigblock can be cheaper to build to get the torque. I dont think a smallblock of the same cubes as my bigblock would ran as fast in my heavy B-body and to me a 63 Sport Fury from the Max Wedge era just looks right with a bigblock. But I am very impresed how strong these smallblock stroker Mopars are running. Ron
