Thanks Scot, he's getting pretty close to having it running now, hopefully by the end of the month. We ordered a set of Moog 5662 Coil springs from Summit, listed on Moog's website as 748 lb. spring rate. He cut off 1.5 coils which is what the average that most S10 guys were doing. That theoretically will increase rate even more but we just say 700 lb. to keep it simple. Right now the truck is maybe 1/2-1" higher than what we're after but we need to drive it a bit to let things settle and then we'll asses how we like the ride height again.
BTW these same springs work in a G-Body, I have them in one of our cars with 3/4 coil cut off to yield about 2 1/2" drop.
This is why I enquired. I swapped a set of Hotchkis 1"drop 600# springs into a g-body recently & it's chewing up the inners (<2k miles). Previous builds I did used a 650# spring but I couldn't find the mfr for this one. The similar g-body set-up using the 650# springs (& similar gas charged/mono-tube shocks) didn't have the buzzing so I need to increase the front spring rate slightly.
Thanks for asking! Yes, it's on the road. It's in the break in period and we're working out the bugs right now. Once we get it past this stage we'll take it out for some more photos and video. I've been with Roman on some part throttle pulls and it'll plant you in the seat. We're both looking forward to the 500 mile mark.
