Good Years or Phoniex?

Not running the class yet.Still running S/P. I would be close to the 10:90 index as the car runs 10:70's @ sea level.The index is 11:20 here @ 2500', I run 11:15's.
Instead of a throttle stop, which I ran on my S/G Daytona, I might use a under carb. stop (slider), because I also would like to run 'D' gas at nostalgia races, which doesn't allow any electronics, with a 4th's Pro tree.(my delay box is on a plug for quick removal)
I have also changed the combo to 4:57's was running 4:30's. When I 1st ran the car last year. I was running 4:89's which were a bit too low, but ran 11:0's at our track..My freind talked me into the 4:30's but with the glide I felt they were too tall.
The car was consistant with the SS springs,, but it "stink bugged" out of the lights instead of lauching foward, which I think hurt the 60's.
As you can see by the picture, this car should be packin' the front tires, which it doesn't.
Thanks for your input.
