OK. The car came from the builder with 25 " fronts. I changed them to 23's to try to help with reaction time issues when I had a sbc. Didn't help, but haven't tried the 25's with the 522. The car was built for a bbc but had a sbc at first....
I'll probably put the 200lb springs and 25" tires back on and go from there. Getting it back on the wheelie bar will probably help more than the smaller tires. So far, the only action the wheelie bar has seen is loading & unloading the car!
I do have a TCI pro brake and an antiroll bar.
Can't really say that I'm like the current IC and don't mind diving under to change it.
I don't think Goodyear makes a D1 33x16 in a stiff sidewall. I know the do in a D6, but I think I stay with what I have for now. If I can get it to go .010 or more red, consistently, I'll be happy....
Thanks again,
Johnny

Good year D-2252 is a stiff side wall with 101 to 102.5" roll out it is a 32.0 X 16 X 15 rim tire and is D1 compound.
Good year D-2071 is a stiff side wall last year with 104" roll + - and is a 33 x 16X 15 and is D! compound. It can be High growth and stiff side wall.

Goodyear 2253 AD has 104.3" roll and 15" tread 15" rim and is D1.
Goodyear 2251 AD has 103" roll and 14.8" tread 15" rim and is D1.
Both are stiff side wall and extended life tread.

A hard hitting converter and a low geared plantery setup, I think will give you the easiest and probably the quickest reaction gains.

I'll try some more chassis adjustments first. They won't cost me any money. My converter stalls at 6000 in Tucson and 5800 in Denver and the car actually reacts better in Denver.
That may be the track, the rollout, or the tree itself. I can usually get close to red there........or maybe my brain just can't handle all the oxygen in Tucson!
