I agree with BIGJ. It'll do it, but it'll be working hard. An '84 350 doesn't make a whole lot of power, unless it's been modified. Heck, I used to tow a K20 mud truck on a very heavy trailer with an '85 C10 with a 305/4 spd. It wasn't fun or pretty (or safe), but it did it. Thank God for that granny gear, or it wouldn't have gotten it moving. /forums/images/graemlins/grin.gif There's no comparison to having more than enough truck for the job, though. It can make the difference between a white knuckle trip to a relaxed, enjoyable trip. /forums/images/graemlins/grin.gif
