What 340 camshaft?

Well...it is an 833 4 speed. It has an 8 3/4 sure grip. It has brand new U joints. I'd like to think I'm smart enough to not over cam it. I drive it a little bit, not very far, and I couldn't give two ***** about gas mileage. I've had the car since June 13th, and I'm pretty sure it hasn't seen 5500rpm.
I understand what ya got. I have a 11-1 - 360 248 duration @ .050 solid cam in a ‘73 - 4spd Cuda w/4.10’s w/275/60/15’s.
I really can't race it. It's got radial T/As, 245/60-14, and those tires don't stand a chance with my engine/ gears now. It is kind of entertaining though!
With tires like this, you walk it out of the hole and slowly depress the go pedal until the tires give. Then you know you over powered it and use a little less pedal next time until you find the rate the go pedal goes down until the tires have full traction under the max load they can handle.
