Vortecpro.

If you wouldn’t mind sharing.
How much front end weight does your chevelle have and what front springs are you using?
Thank you

Good, cause actually I don't remember, but I think I gave them my weight bias.

I`m running the Santhuff 250lbs and wouldn't want anything much lighter for a car that sees any street use, those 200lb springs probably wont be happy with a BB on the street . I tried some 260lb trick springs prior and my car set on the bump stops. I talked to Santhuff and they said you could take up to 2 coils out and it really wouldn't hurt anything. I put these springs in when I had steel heads on my car and the ride height was perfect. I have aluminum now and did remove 1 coil but with Michigan roads I wouldn't want to be riding on the bump stops. The car works fine at the track also with 1.30ish 60` times.

BTW, just in case someone else doesn't already know, Santhuff has these springs in 180, 200, 225, and 250lb rates. When Vinny Laurita was on here and had his son racing their heavy weight 3,900LB GM ZZ 572cid powered 70 Chevelle turning 1.3 sec short times, I saw them both at the track in NY, and they had the Santhuff 225LB front springs in thier car. Not only was it an iron tall deck block, but he also had a stock four core radiator too. No fiberglass on the car.

Vinny told me that out of all the things he did to the front and rear suspension on that car, the Santhuff front springs made the most difference in the way the car launched and hooked off the line. Between his bold statement on that, and the success that Bob West had hooking his "Green Weenie" 71 Chevelle using Santhuff springs, that got my attention. I also think it's great that Mark Jones has shared the details about his car. Very cool. The thing that stands out about what he shared in his post here, (other than him also using the Santhuff springs) is that he has the engine set back. That can make a big difference as far as I know. Even if it's just 4" back. But I'm also pretty sure that takes a lot of work since a number of things need to be changed/modified, to accomplish that.

My car is a 200lbs lighter, the front is 1863lbs, and running those same 250lb Santhuff springs with a 1/2 coil cut off. They work good for the track and agree, wouldn't want them any lower for the street. If my car was a street car only, I'd opt for some stock BB springs.

Brian, you need to move that decimal place. The last time your car ran, that 1.30 was closer to 13.0 along with metal noises that would make an iron worker cringe (sorry, it's been a long winter)

My car isn’t a street car but does have iron heads.
It weighs 1800 up front
It’s also installed with the small block mounts on the saddle.
I have enough room to reach the upper bolts from the top but that’s all.

Re: Vortecpro.

The most important information to have when ordering Springs from Santhuff what the front of the car weighs

Bob, I can't recall why, but don't think the Santhup is the same as a Landrum spring.
