the leaf springs are 20" front segment.
when i ran the car a few years back it would run 9.80's at 135 on motor and pump gas. 493" indy heads, .640 flat tappet, 3350 lbs mufflers and M/T radials. later i changed the gear to a 4.10, swapped convertors and added nitrous and have been 9.11 at 3410 lbs. had some issues to work out , combo will run 8.80's no doubt. i would like to turn it up more, but have a stock block and dont want to push any harder. when i get a good short block together i'll prolly add another stage and get after it.
