Is 2.73 gears ok for a set of 35in tires???
It maybe a slow start but good on gas. I have 32" with stock gears and hate it
I'm running 307's with 33's and its slow off the start. The biggest gripe is that at freeway speeds it sits between 2nd and 3rd on my th350 trans with a stock stall converter and heats up the tranny fluid. 33's a 356's might be a better combo.
What, Me Worry?

That setup will work OK if you always drive down very steep hills. Getting to the top of the hills will not be much fun though. 2.73 is pretty far away from the optimum 4.11(without an overdrive trans) or 4.56 (with an overdrive trans) gears with those 35's.

It's a great day to be alive...
Yeah, it would be a slow start, but it would be terrible on gas. The motor would alway's be lugging at a low rpm. The engine will run hot, and the timing would have to be retarded.
Keep it simple
NO you should have atleast 4:11's with 35in tires 4:56's would be better and if you have a 700r4 4:88's would be best. if you runn2:73's with 35's you will over work the tranny and motor + you would have to have one hell of a motor to climb anything lol
