The cheapest and easiest way is to regear your axles. The other options are a larger motor and that is never cheap. Going to a Dana 44 will give you a stronger axle but it does nothing to help perfomance if the axle ratio is the same as what you already have. Superlift Suspension has a pretty good chart on their website that helps you determine a proper gear ratio using your engine RPM to keep it in a certain range to regain performance with your current tire size. My guess is that you will need at least a 4.56 to 4.88 to get near what you had before. I hope this will help!

The easiest way would be to put the original tires back on (but I guess you don;t want to do that) You could change the ring and pinion to about a 4.11 ratio but that is not particularly easy. Newer transmissions have more gears but are overdrive units and would cut your performance on the highway. . Most Hot Rod techniques will give you more power at higher RPMs , but you need torque at highway RPMs, If you have any doubts about your engine, this might be the time to think V8. Are you sure you need those big tires?

well as was mentioned by the other respondents, your options are limited. a dana 44 axle would be a good start, but remember you ought to replace them in pairs,and would be easiest to order the new axles stuffed with 4.10 or lower ( higher numerically ) gears. you can also consider dropping in a 305 chev v-8 which i beleive should bolt right up to your existing driveline. the reason why your feeling the pain so much is that your buick doesnt make enough torque to turn those 35's. so thereby it has to work harder to do the job,and in order to work harder its gonna suck down more gas.

Changing the ring and pinion is the way that a professional would do it, and if the rear is a weak one, change the whole thing over to a Dana 44. Remember the "weakest link in the chain" theory!
4.11?

4:56 gears would be good. only having a 3 speed i would not recomend 4:88,s cause at 60 mph youd be about 3300 rpm

Run the stock tires on road and the 35's off road........

If your having handling problems try a duel steering damper set-up.
