Don said: >snip< "Ultrdyne has mopar specific but for me the lifts are too high for the duration which is do say they do not match the reality of the iron head engnes." thanks for using the "for me" in your message Don. my car is a fully dressed street car running 11.30's, that is, all steel, full interior, crank driven alternator and waterpump,the only difference from cruise night is slicks. this is a true street car which gets its share of street time! for further drama, it is stock crank, rods and ross flat tops, with worked 452's, simply put this engine is really just heads and a very nasty sounding (and performing} cam. for me, it is hard to beat an ultradyne cam, for price and performance. my car has had the same crane (1.5) rockers for many years and a few different cams, but nothing will wake up the engine like an ultradyne. correct me if i am wrong, but the numbers for racer brown and ultradyne are really not that different, when you consider racer brown says that you must use 1.5/1.6 rocker ratios to get there cam to work. (1.6 translates into higher lift?) on the other hand ultradyne designs there cam for 1.5/1.5 rockers (99% of the mopars already have these) i have never run racer brown, if i have to replace my rockers someday, i would likely look at them. but you can't really compare racer brown to the others, since the others are all designed for 1.5/1.5 (normal) rockers tom 65 satellite __________________________________ Discover Yahoo!
