Moog 5608 Spring rate ok or not

I just got some 5608 moogs and the spring rate is 421 vs a spring rate of 748 for the 5662. I have been searching all day on here to make sure I am going to be happy with the 5608. I will be putting a 350 carbed motor back in along with the 700r4.. Some of the weight has been deleted from the front including AC delete, cruise control. New KYB gas shocks to go on also, with founders CC plates. Im not looking for super high performance just a nice sounding hot rod to cruise around in with the tops out... hence the reason Im going a cheaper route. Im on a very tight budget with this restore project and just cant go with Eibachs and blistens (All the expensive stuff)

So in your expert opinion is these softer springs going to ride ok on my Michigan roads? Not going to be in many curves because the roads here are all straight but they are very bumpy. Also I assume the ride height will be close to stock.

Please help a fellow third gener cause this has been bugging me for weeks now on what direction to go with this suspension.

Thanks

Re: Moog 5608 Spring rate ok or not

Any spring that's new will be better than sock 20 year old springs. Whichever moog spring you get, I would be surprised if you didn't have to cut them a little. I put in the thickest moogs, 5662 or 5664, after I installed them I had to cut a whole coil to avoid the 4x4 look.
