I'm trying the trifecta with my 80. i lightened and boxed the frame, 6point cage and am building a turbo sbc for the 1/4 but i also want handling and maybe even drift the car a few times. i plan to put a 9" rear with disc brakes. really I'm shooting from the hip here looking for all the info i can to build the best mid ground setup that can do all 3. i just want to beat the crap out of the car and let loose the tension that normal driving on the street builds up lol
