Drag Slick Tubes.....whats the life spand???

Thanks Rick!
I have screws but only like 4 on each bead. think its time for a few more of them.

Have gone from a 340 to a 408 with 456 gears and a cam built for lots of bottom end.

Look like i have my plan for tonight!

With my 340 i could put it in 2nt gear, brake it, and mash the skinny peddle (to check my stall) with no problem.
Had to jet my carb up 6 steps last night. With it in High gear my brakes and my left foot are not enough to hold the tire.

I haven't been able to make a full pass because of my "Bone White spark plugs" and slicks that are showing a couple of threads#-o
