Yes, you don't want to be to aggressive. The lower hole works best and you want to extend the shock slower then with a slick. I would recommend a good double adjustable shock. How much power are you trying to hook?

Auto... 8" converter approx 5000rpm stall, 4.11 gears, 275-60-15 Hoosier drag radials. It will hook if I load the converter to 2000rpm but it doesn't hit the converter hard enough. Load it to 2500 and it spins.... 60 suffers regardless.... Best 60ft was 1.53 it runs 10:60 at 127mph.... I have Calvert single adjustables I haven't tried the bottom hole been all over with adjustments on the top....

I would try lower hole, 1/8 airgap, full tight on shocks. Front needs to be loose and have 5 inches of travel, hope you have some 90/10 in it.

Back at that power level I was able to go 1.42 60fts on 295/65 hoosier radials. My car also liked to be flashed back then, 1200-1400 at line and it would work best that way.

I've got the 90/10's and the required 5" of travel. I've been putting more preload in it trying to hit them harder... That's why I was thinking its time to go the other way....

So what does the 1/8" gap do vs the stock 2 flats setting that calvert suggests you start with? And how do you set the 1/8" gap? With a .125 shim then pull it out?
Yes I run .060 gap in ours.
To the other racer how much air you trying to run in the tires ?

Not to hyjack the post, but mine are in the top hole...should I change them? Haven't run the car yet but hoping to get up in the next 2 weeks. I'm running the MT Radial Pro's. and crappy Comp Eng drag shocks. I'm just looking for 1.52-1.55's

Mine are in the top hole also, rear shocks set on 9 and the the bolt just touching the spring. I am think about moving to bottom hole to see if it will com down the front end when it leaves. But it hooks good now. I am running M/T 315/60 Drag radials. 1.33 60 ft.

Do you always race w/out a hood? Cos I`m thinking there`s a few mph w/one on............ 
Thumper check the thread out that I posted ( hood and scoop color with pictures)I think it is on page 3 now.I don't want to hijack this thread. Tell me what you think.
