Does anyone have recommendations regarding the best settings (caster/camber/toe) for a mainly strip and sometimes street alignment? Stock front end.
Great web site.....thanks for any information.

I'd use
0 deg, to 1/4 deg negative camber
As much positive caster as they can achieve and still have the 1/4 deg neg camber, RF should have 1/2 deg more caster than the LF. It usually works out at 2.5 RF, 3 LF.
If you have manual steering, the added positive caster will increase steering effort, I don't know by how much.
Toe: set 1/8" IN total.
This is pretty much the normal street alignment I recommend, but just a bit less neg camber and a bit more toe in, it should work well on a drag car.

Matt, I think on a true drag strip car you should check out David Pozzis' page regarding "bump steer". First gen Camaros have a lot of it.

On a drag car make sure you scan down to bump steer and forget about the road race modifications. His modifications of the steering arms will get the bump steer down to a number you can live with.

I strongly advise measuring your bumpsteer before doing any corrections, don't just do the same as I did, or it might not be an improvement.
Note that at high speeds on a drag car, the nose can lift and cause toe-in at significant amounts and lower your top speed.
I don't have much drag race experience so my alignment specs are a bit of a guess but the bumpsteer issue can be important.

Also take up the lash in your steering box, it usually helps in straight line tracking.
