It depends on the track size and banking. I run a 1/2 mile very tacky track, with good banking and long corners. I run 200rr and 225lr with 3300 pound car. Tried 175rr and 200lr last year and it was way to soft!!

Keep in mind that the chrysler leaf is shorter from the front bolt center to the spring center bolt than the chevy leaf.
Will need to relocate front mounts or just use a shorter wheel base.

These guys are right in there on the spring
rates. Back when we used the leaf springs i would use a 200-225 on the R.R. & a 225-250 on the L.R. Also what i found to work best on arch was 5"-6" on the R.R. & 7-8" on the L.R.On the L.R. make sure you have two of the straps that wrap around the leafs on the front half,on the rear part take the straps off.This will let the spring work better when the L.R.drops down as the car rolls over to the right. on the R.R.leave the straps as they come.Also if you can use a 9"shock on the L.R.& have it set so it can extend out 5" & not hold the L.R.up on roll.Also the L.R.shackle length & angle is very important.It will make a big difference
when the track goes dry.

the chrysler springs seem to hold up a litle better. and they are shorter which in a way is good. i move frnt mounts back about 2 inches and use the adjustable brakets that way you can adjust ride height, and pinion. and on the back i drill a hole in the frame and install inserts where i can get shackle angle correct. nothing to hurt you worse than a binding spring shackle.

Switching to the Chrysler Springs will definitely help forward bite.
