A few weeks ago I blew up a set of 4.30 gears that were in my car. All I had was a set of 3.23s so I threw them in just so I could continue racing the rest of the season. I had 30" tall drag radials on it. So I figured with the 3.23s I would need all the help I could get so I threw on a set of 26" drag radials. Now the 4.30s with 30" tires comes out to be roughly 4.01 ratio and the 3.23s with the 26" tall tires come out to be 3.46 ratio. Much to my surprise the car had the same 60 ft of a 1.53 and the same 96 mph and same ets 7.08 in the 1/8. So now im thinking what to do for next year and wondering why nothing changed.
I had jetted the carb up and down before and it didn't change anything either.
Im starting to wonder if the head flow is where the loss/no change is.
What everybody think?
