my pal reakons they overkill for my situation, ie street use, i do not want it "all or nothing power" he reakons have my iron heads cleaned up,re seat valves,3 angle etc and a properly matched cam to suit<think thats where so many people go wrong> my motor is a 65 440ci,edelbrock performer dual plane inlet,holley 750 vac sec,shumacker headders,msd 6 ign,single point dizzy. i think the guy parting out as he bought it because "somone else suggested/using same/looked good huge hp claims etc" was a mis match of bits,had a tantrum as it didnt perform now realises a good cam would have been his salvation.
