I recently purchased a 84' chevrolet silverado 2500 with a 350 engine and 700R4 transmission. The truck is lifted 6" and has 35" tires, being an overdrive transmission will this lift and tire kill this transmission or will it be okay? a friend of mine is totally against this setup and says it will end up in the scrap heap if I don't buy another transmission. Plans for truck is a Daily Driver with limited use offroad, I may tow with it some time but rare. He has got me really thinking I F'd myself on this deal.
