Which springs to use for a big block 4th gen? I have a the QA1 set-up with the 275 drag spring, but now I have a big block up front so those aren't going to work. Any one know which ones I should use or what size to get?

thanks, joe

 

You could get a set of BMR (SA001) Spring cups $59.95 pr..
Then you could use a set of 1LE front springs since they have a 360 lb.in. spring rate, or a set of SLP level II front springs with a 450 lb.in. spring rate.
You could use just about any lowering spring available for your car, but the spring rate would likely be higher than you would want.
