How to Modify Stock '72 GM A body A Arms for more Travel?

[1320racer]

GM A body cars of this era need as much front end travel as they can get, never too much and therefore no need for travel limiters.

Thanks guys

What would be a good drag racing alignment set up Stock A arms specs?

72 GTO 3400 pound, 455, Turbo 400 with 5000 stall converter? sometimes with Using the trans brake, 4.10 rear gear, 10.5W x 12 M.T. bias slicks

Front: #200 Tall Landrum Front Springs, Double adjustable AFCO Racing Eliminator BNC2 Valving Shocks 3850F/BNC2,Offset front shafts, bump steer correction steering knuckle levers, good bushings and low friction ball joints, travel "5.5

Rear: Double adjustable rear shocks with full-length adjustable ladder bars.

Pulls the wheels 2 feet and runs 9.90's - 10.10's at 130's with 1.38 - 1.44 60's

Thanks again for all your good input.

On alignment specs, I believe you?d want 4-5 degrees positive caster if possible. About 0-.5 degree positive camber and try to keep that thru complete motion of suspension. And 1/8 degree toe. I know there is more to it. I used a race shop. Now retired. I haven?t touched a thing in 7-8 years. Afco 80/20 fronts, Gm 42h0042 springs, global west bushings and the pro forged +1/2? tall ball joints. Stock lowers. Car sits nice. The upper ball joints have what I think for at least my car too much travel. I have photos. Rear has bmr trailing arms HR parts anti roll bar and 4.30 gears. Viking dual adjustables. 5000 stall on brake. 555 with throttle turned down to run 10.0 and goes 1.32-4 60 at 3960. 295/65/15 Hoosier DR2. Radials. Plan on a front shock upgrade this year thru Marty Rinehart.
These A bodies are a lot of fun. Wish I had a killer stocker big block engine. But 10.0 is perfect.
I?d seen Ed?s Chevelle fly. It was a real well thought out and put together car. Very consistent.
