What rear suspension for bracket racing.

Thanks for your input. All members on this site have given me outstanding information. I need to incorporate all this knowledge to make a stock appearing 70 Swinger 340, with modern horsepower. I'm walking on a tightrope, but she'll be an *** kicker no matter what minor mistakes I make. I've gained a boat load of knowledge from the more experienced members here. I'm driving on. Block has been sonic checked, line bored for a Molnar crank, studs for a windage tray, H beam rods, and Mahle pistons. I got my TF 190 heads, and waiting for my machine shop to get up to speed. Chassis mods will be installed as long as it "appears" stock. Thanks to all members in put.
