In your situation I would keep the sbc since it's been rebuilt already. Now if you needed a new engine that would be a different situation yes It's nice having a new power plant in but if your not going to update the rest of the truck it's a new heart in a 50 year old body.

And it's very easy to get upside down real fast. I've had discussions with guys who have done the conversions and I always get the it gets better mileage now and it's so smooth now. I counter with you get 16 to 20 mpg now but you drive it 1000 miles a year so where are the savings I have nothing against doing the conversion but just say you wanted to do it. My trucks will cruise at 75 to 80 mph with ease just came back from the c10 nationals doing just that. I was being paced by a couple of younger guys leaving TN they stopped when I did and were almost shocked that I had the original power plant in the truck. I averaged 12.5 mpg
