fred, thanks, that site helps alot! did not know that was there. mike, thanks, i needed that too. cool car, alwaysed loved those olds. so if i read it correctly, i can run f with more weight. i did weigh car couple of years ago, 3185 with 1/4 tank of gas with no spare or jack, without me in the car. if car weighs 3200 i can run it as ihra ff/sa. good heads, short tire with lightweight wheels,electric water pump, and maybe a cam, i can at least run the 16.30 index. mike, our cars are similair as far as weight and motor goes, what have you done to your olds. i don't need every little detail, and i know a higher ratio final drive will make a world of difference, are you at 430 lift? nothing is done to mine as far as performance other than no cat. i still need this to be streetable, still have all power options and air and i still will have all these on car no matter what. ed, turbo car is out of the question. i know a turbo fwd car can run the index, but this is just to tide me over until s10 is finished. i enjoy going to the races and hanging out and helping anybody that needs help, but i want to be "in the beams" so to speak. don't know if i will have everything done to it by reynolds, but i'm going to try. even though new ssssa rule is no protesting, i don't think i can tell jim car is ihra gf/sa, and get away with it. rick.

Rick I might have a set of 20" tall 8 inch wide slicks, mounted on 6 inch wide American racing rims 5 x 100 mm bolt circle, for sale. You can try them if you want at the Valdosta race (if I get my transback together). I'm going to a larger gear so I'll be using 22's or 23's.

[rick lester]

thanks art. i was at valdosta race this past weekend and had a blast. i wanted to meet you, but after you broke i thought i'll wait. i might buy the slicks, but i need a 5 x 41/2 bolt pattern for my olds. yes a ford wheel. i run 98 ford mustang cobra 17 x 8 wheels on my olds without any mods. in mm i think is 5 x 114. let me know if your going to reynolds. rick.

Hi Rick. Yes, a car that is a natural E car can run D and F legally. Is your Olds similar to the Stephenson family's car? It's killer fast, holds the DF/S NHRA record at 14.72. Pics can be found at http://www.autoimagery.com/store/cgi...ole+Stephenson
Mine is a .422 cam. I bought my car from Tom Kasch in Ohio in 2006 (Stephenson's Olds is a former Kasch car as well). It's a neat car, power everything, even seats. All leather interior and a sunroof to boot. Both the car and myself need to go on a diet (myself more so LOL), as it weighs about 3500 pounds, a hundred over the DF/S-EF/SA minimum weight.
