I've been reading in some earlier posts about the best driveline combos. i have a stock 59 3800 1-ton with a 283, 4speed bulldog and 10 bolt 5.14 rear, and weighs 4100 lbs. i want to replace the 283 with a sbc 350 and th350 tranny from my 82 c-10. Will this combo with the stock rear get me to highway speeds, 60-70 and not kill me on gas? The rear as only 47,000 miles on it. I can get to 55 quick with the stock setup now, ( with eldelbrock intake and 4barrel carb)but i think it's running to hard to keep it going any faster. Any ideas?
