Car is a '90 Firebird, a bracket car. Small block, TH400, 3.73, 3500 converter, 28" tall MT radial tire. Runs 10.80-10.90's at 124mph with 1.44x 60'. Suspension consists of 90/10's in the front with Moroso trick springs, 50/50 in the rear with V6 springs, Spohn torque arm and tubular LCA's.

The 60' can be inconsistent at times and I'm looking for ways to improve. I've been considering switching to adjustable shocks or coilovers but need to learn more before I do. Can any of you help point me in the right direction?

This may not be the best, but it's an iPhone video my wife took last weekend.

Seems you have the right stuff.
Consider adding weight to the back, no cost.

The Torque Converter does not need a hard STR like a Stocker.
If you have an computer electronic system.
Retard the Launch Timing to soften the hit.

Get rid of the Radial Tire. Back to the standard Slick.
Radials are a cause of inconsistency.
They work when they work usually with well prepared tracks.
They are not at all forgiving when the track prep is not spot on.
