A problem alot of cars have is to much rake which also has the side effect of giving you way less caster. Caster is probably the largest contributor to high speed stability out of all alignment settings. Lowering the front will not help this condition whatsoever.
Mopar to the bone!!!

Thanks for all the responses. I think I'll try lowering the front end and checking the alignment/steering linkage first. The car is back halved so I can adjust the rear height easily. I run 8 psi in the slicks. The front suspension has been updated to disc brakes by swapping everything over from a 73 A body. It does seem like the front end is sitting high as I go down the track. I didn't know it was possible to block off the grille and still keep it cool. I added a whole car pic so you can see how it sits.
theres your problem, the rear is setting lower that the front. looks like the front is at least 5" to high. looks like the wheel is leaning in at the top just setting there. lower that thing and reset the alignment. and you don't need to block off the grill

if your ladder bars are to high in the front that will make the car unstable also. My car has a open grille and I have been faster than 175 with no issues at all. I have recently added a 1969 Camaro front spoiler to help hide the belly pan and blower and saw no difference.

not much gain with only a couple of inches, maybe a few more might make a difference.

Am I the only idiot that noticed your blower isn't a side slinger anymore like all the pics you normally post? You owe me a reply on the other site you know....

"I don't consider 8 psi as low" Rebel at 2900 race weight that may be true but I know that my car at 3600 race weight is all over the track on top end at 8 psi. I don't think we know what his car weighs going down the track at 130 440 Brian how much does it weigh with you in it???
Very true... its about the weight.... I run 7 psi on my car but at 2400# and its totally fine.. but a car at 3600 would be squirming all over on top end.. but I dont know his race weight.... weight VS tire size makes a BIG difference
