1/4 mile times

More cam yes but... that would be a diff combo all toghter, so for what you have, for sure at least a 4.30 or 4.56 gear, larger carb will help the top, but the 60' is the main issue. The gears will help with the convertor.

On a big block with a lot of torque the convertor should flas quicker, my bet is you should be in the 3500-3800 stall range

So suspension/gears and make sure it is tuned right. That baby should leap off the line with a 440 in her. You should be able to pull off a 1.7-8x 60'

PS what model 750 holley carb are you running? maybe lean, weak transistion circuit et. I think a 750 is a little small, but if anything that should help the 60' if it is not to lean or way to fat etc.

Also what is the initial base time and the total timing you are running, and at what rpm is it all in?
