I've said this many times before. Blame the demise of Outlaw 10.5 on the tire manufacturers. Totally their fault. 100% When we started racing when we got a set of tires that were 102" rollout we were so excited. When we quit they were regularly 106" + then they went to the 16" rim and I have no idea what they are now. When we were 1500 horses down on power and 20 mph down in the eighth with a Fulton 762 on 4 systems in the new car and had to switch to the 16's to have a snowballs chance in hell, I told my brother let's sell everything we don't have a chance, I knew we were done.
We started in the first car. (In avatar that car was my absolute favorite car) with a 632 and qualified 2nd in Huntsville the first big race with a 4.58. We were number one , then Petty and Lynch unloaded the car back out of the trailer (they put it up thinking they would let their previous time stand 4.60) and then proceded to go 4.56. At will. Stupid me, should've seen the handwriting on the wall then.
We left at 3200 rpm on a 30/34 Viper kit with 14 degrees out with a 6.04 total gear ratio at the hit. Bottle pressure at 800 lbs. Just to calm it down. Second system, a 28/32 kit came on at 1.2 seconds in. Third was just a tickler kit 20/24. Couldn't even see rhe third system hit on the data logger. We tried 24 different converter combos that year. Played with so many things. Those were fun times. A little motor could compete. Proudest accomplishment was we never, ever burned that motor up. 400 passes. Never. Sold it to some Grudge guy that went 4.10 in a complete pile of crap grudge car later that year.
I will never forget talking with Jack Barfield when Steve Kirk went 4.56 with the Hoosier tire. That thing looked like a stream roller. Jack said, that big ass tire will be the end of this class. (Or words to that effect) You know what? He was right.
