I'd bolt on a 2 barrel and a nice set of headers and you'll get better mileage that way( and a little more power). I have a 600 cfm edelbrock 4 barrel and headers on my 292 and it gets better mileage simply cause its not starving for fuel. I also have an HEI on it as well. You can check out my build for more info(link below). As said a TH350 auto would help alot...also another good choice would be a richmond non-od 5 speed. Gives you 5 close ratio gears which would help in down shifting..and I will repeat, This isn't an OD trans.
cool info. you guys are awesome over here. Got the link from the H.A.M.B. I'm lowcad61 over there.

I have been looking at a clifford / holley 390 set up with Langdon cast headers. I would entertain a 2bbl / glasspack just because of cost savings over the 4bbl / header. I want to keep the six even though I can buy a goodwrench 350 for the price of the six mods. Just dig the OG factor.

Who makes a 2bbl adapter for the intake?

I would definitely look into an automatic swap if I am going through the trouble. That is how I ended up with this truck. Cheap parts and easy auto swap. I am looking to get out of my 94 Mustang GT daily driver. Been sitting down that low and rowing the T-5 for 201,000 miles. My left knee is on the way out and Trucks are more ergonomically correct for the body. I drive 75+ a day.
