Coil Springs replacing leafs
I'm building a 46 Chevy Pickup with a 72 Nova front clip, I'm wanting to replace the front coil springs and I'm putting coilovers on the rear (Dana 60 rear end with coilover mounts).. The truck weighs 2600 now and will hit right at 2900 when completed. I'm buying a complete front end rebuild kit for the old 72 Nova half and while these "stock springs" could be come by easily - I'm really building this old girl for sometimes-Street and alot of 1/8 mi drag - so I'm wanting to get the best weight transfer I can. Anyone have a way to determine what weight coils to use - I'm not so concerned about "ride comfort" as with function - as this will get limited street use (400 cu in SBC motor - 400 turbo w/transbrake - 5.39 rear ratio diff)... and Thank You.

Bout all one can do is make a guess as to what may be required..the guys you got the springs from may have an idea..but all things being equal I would expect to have to change the springs out at least once or twice until I got it right on the money..

Drive style has alot to do with this as well as the suspension geometry..

Wish there was a better answer

My opinion................for this application...........don't use a Nova clip. It's quite heavy, you need something lighter. Maybe Mustang 11............

You are going to have enough problem with weight transfer. Pick ups are notorious for light back ends. Might want to add weight as far back as possible, so any weight off the front is a bonus.

Don't get me wrong, the Nova clip is great for the street, I have one under my 51 Ford, works great.

Have you ruled out an air ride set-up? Up when your on the street and down a little at the track.

Just a thought, that way you could have the best of both worlds.
