77 Nova Setup

To be honest I feel that your front end Is a bit soft, just as an opinion. I don't know how much banking your track is, It may be decent if its flat, if more than 10 deg, I'd be upping the rates a bit, I run a camaro on about 18 deg banking. Springs are RF 1200, LF1000. RR 200, LR 225. It's quite stable with good bite. I would think the best place to measure ride height would be the pinch weld on the rocker panel. As for what ride heights, I'm not sure since I can't use blocks or jacks. If its flat I'd go high, if its banked I'd go a bit lower. It's all in prefererance. I would try your blocks opposite put the 2in drop on left, 1 on right. Afco has a good tech article on leaf springs and shackle angles I have been able to use most of it with good luck. I scale my car without me in it. I start mine off 53% cross ( LR 75 bite) I acquire that with offsets, 3off across rear, 2off RR if track is heavy, I cannot use lead or blocks, I'm assuming you can use lead if there's a weight minimum. If so I would put it as close to the top of the rear end as possible( not on it) with leaf cars I have found most success with getting drive off LR. Hope this hels a little
