sounds like a total clusterfuck.. i didn't have any of those issues with my 64 valiant with a 440 in it. with 6 cyl bars i agree would suck on the road.. i stuck 383 bars in mine and it drove damn good on the street and hell with the 1"+ bars on the market today that ***** would be great on the street, add some alumn parts and even better.. mine never had over heating or steering shaft issues but i was running headers which made plugs easy to get to.. i also kept the stock heater in it and stock blower motor that many say can't be done.. my dual pot master cyl was in the stock location too..
