Looking for some motor input.

I've never joined a forum before but am not finding much info for my questions
I bought a 1977 F250 Ranger Camper Special super cab from a elderly man about a year ago. It appears to be all original and is rust free but has the battle scars from over the years. I'm not a mechanic but due to finances have always done my own work and learned the hard way.
I was hesitant to buy the truck as I was unfamiliar with the 460/C6 set up. I did have a 74 with a 390 and a 60 something with a 360. Both had 3 speeds.
Over the last year I've been impressed with the power the truck has towing a boat with a 3k camper. That said it is old. The only mods I can see are a extra tranny cooler and a aftermarket radiator and a true dual exhaust. The steering assembly looks like it's been redone. My questions start with the factory cruise control. The wire has been removed from the linkage but have no idea how to reconnect and adjust it. The second is I have noticed white smoke from the drivers side exhaust only. It stops after getting it warmed up. If both sides would assume its condensation. I've seen reference to timing chain but not sure how to find tdc. I want it to be reliable but would like more torque at say 55-70 mph. It doesn't ever get hot but with a load it feels like it's pushing max going up hills. However it never has to go over 3k rpm. It has a 4:10 rear but the swing bearing makes me nervous with towing and souping it up.
Guess I'd like some experienced feedback on what would be a moderate build up and some ideas on a process that would allow me to build as I drive.
Any help or questions are welcome.
Thank you

That is most likely as a result of the heated crossover passage/heat riser valve.

Re: Looking for some motor input.

The later 460s still had a lot of potential

What I would do first, is swap the timing set for an earlier version. Unfortunately it's not easy to tell what is in there now, so buying one for say a 69 429/460 from a reputable company that lists a different part number for a 1977 460 should get you there. If you consider it, post part numbers here and we'll check

Your comment that you do not rev it high is fine, actually better, the later timing sets retard the cam timing for emissions, what that does is shift the torque curve higher, so by advancing the cam you gain vacuum and torque, and overall the engines run better

In addition, while it is apart I would consider having the distributor recurved, there are 460 guys around that can give common standards for stock motors, but I would shoot for 12 degrees initial, 36 total, all in by 2800-3000 rpm

Third, I'd put headers and good duals with a crossover pipe, X or H, and I wouldnt be shy about exhaust pipe size, 2.5 inch to 3 inch, whatever fits in nicely, most shops will prefer to work with 2.5. If your current duals are 2.25 or smaller, they'll do fine for now, but realize that a 460 is a pretty deep breather and they like exhaust pipe diameter.

Finally, a shift kit, probably Transgo.

Those changes alone should get you better mileage and significantly more hot rod feel as well as torque in the mountains. Matter of fact, I bet it'd outrun 1/2 of the "hot rods" you encounter

When you are referring to the "swing" bearing, do you mean the two piece driveshaft and the carrier bearing that supports it? If so, don't sweat it, it's strong, the only concern I would have is with very high driveshaft RPM due to balancing and all those pieces working (or not working) together. But from a torque perspective, its plenty strong. Every tractor trailer on the road uses that design.

Re: Looking for some motor input.

regarding the mid mount bearing on the driveshaft.
It is called a "carrier bearing" and it is not a problem with power. Timken sells one that is available at Autozone and a local machine shop should press the old one off and a new one on for $25 or so.

amen to that- my stock '79 (rusted-out ex-farm truck) will flat-out embarass you if you'e not careful...

with that said- i can't imagine a 460/C6 running tall gears wouldn't have all the torque you're looking for already.

how many miles are on it? have you done a compression test to see if the engine is worn out?
