Hey, guys, I'm scratching my head whether to stick to the stock turbo 350 trans or go with a 700r4 for my '70 Impala powered by a stock '72 400 sbc. The '70 has 2:73's now though have been told it's not wise to use the
700r4 with highway gears and stick to the t350. I know with my '86 Caprice with a 9C1 350 and 700R4 I got in the 20's MPG on road trips. Kind of want some kind of decent highway mileage with the '70 as well, thanks
