i have a 71 rs lookalike with 585 chp all aluminum dart 434 cubic inch sbc roller motor with mass flo efi. i do not do track events but it is a really solid car on the street. after corner balancing the weight distibution was slightly more evenly balanced front and rear. the car weighs 2250 pounds give or take a gallon or two of gasoline. it has all the usualy brake and suspension modification with lindsey 17 inch wheels, big bars, big brakes, mattre aluminum roll cage which does help to stiffen things up a bit. with the 930 transaxle and aluminum trailing arms the car cruises at 70 mph and 2250 rpm and gets much better mileage then my 930. i prefer this car over my 78 930 and the 930 is seldom driven. both cars are setup similarly as to suspension, brakes, bars, etc. the 930 is efi and to get the 425 rwhp it was much more costly. so i am partial to a v8 porsche because i can get really high horsepower per dollar invested in the motor and it does not require a specialty shop and mechanic to maintain. not for the purists but it is for me!
