Well, all this information is great, and I understand more than I did about modifications that can be done. But, it's also discouraging. The FI sounded like a good idea until the issue of electric fuel pump emerged. At this point, it seems that it would be very easy for me to go down rabbit holes of modifications of ever increasing complexity and expense. In addition to the cost of these expensive mods, I would most likely have to have a mechanic do most of the work. And, to find a mechanic who actually even knows what a "Slant Six" is, might be a challenge. I think I would rather focus on what modifications might be closer to my skills, and budget. Then again, I could just leave it alone and drive it like it is. Kind of disappointing, but a lot less work and money. Working with wood and on houses is a lot easier. Oh well.

Fuel injection is great, but at the end of the day you'll be $2k lighter and still have a wheezy little turd between the fenders. Your wagon is heavier than my sedan and that motor realistically probably only produces 90 horsepower. You can add the typical bolt on and probably be somewhere in the 120 horsepower range. After you tear into it to increase the compression, do some head work and change the cam you'll be somewhere in the neighborhood of 175 horsepower and still not produce the torque a factory built 318 will. Lots of expense for very little gain.

Honestly, if you're not willing to commit to a V8 swap I would leave it all be.

If your wagon is like my Aspen originally was, I can completely understand your wanting to up the power some. Mine had an E24 California emission 225 (for some unknown reason), rated at a whopping 90 hp. Even with the 4-speed and 3.23 gears, acceleration was, well,,,,,,,,,, leisurely. On the freeway, on the slightest upgrade you'd need to downshift out of O/D to 3rd to hold speed. ............Engine was fine with only 71,000 miles so it had as much power as it did when new. Of course I ended up way over compensating for the lack of power, lol. Back in '88 when my buddies GF blew my doors off in her bone stock 6 cyl, 3 on the tree '67 Camaro, I knew something needed to be done. :p (Yes I know a base '67 Camaro is a lot lighter than a '79 Aspen, but still......)

If I were you, toss a 5.9L Magnum in it. Keep the motor factory with the fuel injection. 245 horsepower and 330 ft/lbs of torque with all the driveability of sequential multiport fuel injection. Use the 833 four speed you have now. Run it with V8 exhaust manifolds too (no headers). All OEM components means OEM reliability. This would make for one sweet ass driver.

Sure, fuel system would need to be retrofitted, but it's not crazy. You could get away with running the pump externally if you wanted to.

Thanks guys for all of your input and advice. I have a lot to think about for when I finally am able to get back to playing around with OY. For sure, I think I better replace the timing chain sprockets at least. I am kind of overwhelmed and a bit disappointed that there isn't some less involved and expensive things that would give me at least some of what I am looking for. But, it's not bad the way it is, and thats ok. It managed to make it home to PA from CO on interstates back when I bought it, and had no problems keeping up with the traffic too. It's purpose is really just to be a part time cruiser for me and to have fun at cruise nights and such. So...
