"a correction CM: He does have lighter spring tension torsion bars , RUNS TRAVEL LIMITERS."

I see a problem there, friend had a 427 Vega, very hard to hook the tires, no rotation. He sold the car and the first thing new owner did was remove cable limiters off the front a-arms. First time out with no other changes carried the front wheel 1-2 ft and would hook on snott and picked up 2 tenths.
Original friend wanted the "pro stock look", didn't like the tires hanging down on launch.
