thanks to all respondents,all good info. i have this posted on the a- body side too,and have received some negative reactions from what i would think are serious h.p. racers,of course its not for that use you build one today,but for the novelty,just as a 440 in my dart is ,of course we all know you can build just as much h.p.in a small block that fits comfortably in the engine compartment,but we sometimes like to be different.again thanks to all and to all a goodnight,i forget who used to end their show like that ,but i have forgotten alot ,since growing up in the late 60.s and 70.s
