I would start by replacing the shocks with a set of single adjustable coil overs and the right spring. I ran strange shocks in my car and 130 and 138 springs. But my car was 3200 lbs with me in it. I went 1.25 in 60’ with the singles and with more power went 1.21 with the double adjustable shocks. Set the car height and see what length springs you can use. It looks like the lower mount can be flipped over and give you much longer length on the shocks.
68 ladder bar coilover choice n dialing in what’s ur car weigh????

Ok so I have an iron headed bbc car that’s back halved Dana 60 ladder bar n 33x 22 or so street radials. My coilovers have the adjustable perches off the axle they are eye to eye and I have two sets up upper holes to choose from that are only an inch in difference in height. The lowers perches I can move in increments of I’d say an inch in either direction. Currently the car has old vw shocks (for extension length purposes) and a set of 160 lbs in coilovers. Due to using what came w the car and in the trunk factor upon purchase I felt putting these together to see what I had in the end. Well I had to adjust the coilovers to maximum height to clear the freakin balloons of the tires out back I feel like the only give I have on pushing on the bumper is really just the air in those huge tires I’m feeling like I’ve basically locked the operation of my rear suspension w these coilovers. What’s a great place to start sorting this out? Imma weigh the 68 when my knee is better I just had surgery just wanted to know if anyone else has been here before

The bar angle sounds fine to me. The fact that the driver side is up a little bit shows a little preload for the driver. My bars were a few degrees down in my car.
I ran the car with multiple combinations and gear ratios. I had run it with 4.88’s going 9.30’s to finally 4.33 gears when I sold it going 8.80’s. The car started with a 750 hp 509 when I first did the back half and then was sold with a 980 hp 565. Never once did I move the ladder bars. I started with single adjustable strange shocks for 10 years and then went to double adjustable for the last few seasons.
