Is it wise to push a 7 1/4?

when i built my moderate 318 in my 67 dart it ran 14.60's with 2.76 peg leg 7 1/4. that was with 215/75/14 tires. i went thru three rears before i got an 8 3/4 under it. if you go to the track. DONT LAUNCH THE CAR. just roll into the throttle. its the shock that kills them. it will still be a blast and you should get an idea of what its got by the mph. light goes green and just gradually press the gas peddle down. should be flat to the floor before the 1/2 shift.

my car went from 14.60 with 2.76 gear to a 13.80 with the 3.55's and detroit locker.
