Suspension?

Got a 70 Dart and putting a modern stroked hemi in it. Will be a carbureted 394 cubes with a 727 or 904. As far as rear suspension I was thinking of putting some super stock springs on it and just wondering if that will be OK. It will be a street strip car and I don't want to break the bank on it right now . I'm moving the perches in 3 inches to get some wider tires in the stock wheel wells. Is there any other spring to use besides them like the XHD or are they the same. Also what shocks work decent for both road and strip I'm assuming some type adjustable shocks. It will retain the 6 cylinder torsion bars as well. Also if it matters I'm using a 8.8 Ford rear...I know I know lol but hard to find a A body one as cheap as these with disc brakes .
