Front springs

[BoostnTtype]

I am going to swap a ls1 into my Ttype and i was just wondering what springs i should use because of the weight difference of the motor. Thanks.

Rather than start a new thread I'm bumping this one back to life.

In my case i'm looking for about 1.25" - 1.5" drop from the springs. The car will eventually meet my iron block Ls 6.0 (estimate 510 lbs). As of now I'm thinking Moog 5658 with half a coil cut and start trimming from there. If all falls into place i should have some Qa1 single adjustable shocks in all corners FWIW.

What are some tried and trued combos?
