My 70 Duster runs out of rpm about 2 seconds before the 1/4 mile traps. Currently have 4.56 gears and 12.0 x 29.0 x 15" slicks. Nobody makes a 12.0 x 30 or 31" tall slick. Next step up is 13.0 x 31.0, but only tube type are available, so I would be buying tires and tubes (currently running tubeless Hoosiers). I don't trust myself to get the pre load right, so I would spend some $$ to have someone change out the gears for me.
In the current setup It runs 6.60 1/8th mile consistently and 10.2/130mph 1/4 mile with me backing off the last 2 seconds.
I can't decide whether to do the tire swap or the gear swap. What would you do if it were your drag car??
