73 B body suspension question
ok all, i think i finally got the right plan for my 400 build . now i am curios about the entire suspension - i am going from a small block to a big block and i want to rebuild the suspension , using new springs and polyurathane bushings all the way around ..... is there a difference in the springs or where they the same ??????

Mopar "B" bodies don't have springs on the front suspension. They use torsion bars. If you're going from a small block to a big block then you'll probably want to swap them out for the heavier duty torsion bars. They'll handle the extra weight better. Out back you'll want to go with a set of super stock springs. Both the torsion bars and springs are available at Jegs. The springs go for about a hundred bucks and the torsion bars are around three hundred. You'll also want to make sure your differential has a pinion snubber. Mopar added those to big block performance cars to eliminate spring wrap.
