What is the best pressure ifyou are racing a 3600 lb nova with 12 bolt posi w/ 3.31's and traction bars. She has a 3000 stall on th350 tranny and about 370 horses. with this she still begs for traction. Et streets would be great but for now, its on bf street radial t/a's. Also, is it good to heat them up pretty good or would this not help since they are street radials? Thanks!!
