I have a 72 cuda with 528 indy aluminum block, roller cam and lifters, 1050 holley dominator, 5 speed, 430 rears, 10.75 cr, power steering frame connectors tubular front end with coil overs and rack & pinion. It is fun to drive on the street with the hydraulic clutch. 65MPH on the interstate at 2500 rpms. You can even hear the radio pretty good also because i put stick on sound deadner on the entire inside before i put it back together. Not a race car and the guy is right about not enough tire to begin to hold it down. 700+ HP. Love the beefy idle and the sound when you touch the pedal. It is more fun to drive that the 408 stroker i had in it before.
