I'm fixing to purchase my qa1 r series shocks, but can't decide on which springs. I've read that you need the beefier springs if you have an iron block.....Just need some imput before I buy them.....lq9 408......

Thanks in advance.

 

If it's a drag car I'd run the 300's

 

No, it';s a daily driver....Iron block 408 zero weight deduction driven about 250 miles per week.....I just need to know whether 275,300, or 325 lb springs....I was told to go for the biggest you can get....I just wanto to be sure..

 

I ran 300's with a TT. Too soft for the street. Went to 325's - perfect.

 

325s with the iron block

 

Thanks for the info guys....Looks like it's 325lb springs for me......I'll be ordering in the morning.....
