Since deciding to keep my '74, I've been trying to formulate some long-term plans for it. First, a bit of backstory:

Factory 318 car bought in 2019 as a light project for taking to car meets and running down our local 1/8-mile strip. The vinyl roof was coming off in chunks, so that was stripped and the car was repainted in what I call "Tupperware Tan". Close enough to the original color.

When it came out of the paint booth in July of '20, the world was shut down, I was furloughed, and the car was put into storage at my dad's farm. I worked on it from time to time, buying parts and getting advice from you guys.

Earlier this year I put it up for sale. Having to keep it an hour from house meant that I wasn't driving it much, plus I had to move two tractors and sometimes a 4-wheel-drive to get it out.

A couple of months ago, a storage unit in my neighborhood came available and I snagged it. It's just a place to keep it indoors, but it's only 5 minutes from the house. So I decided to keep the car.

Since then, I've driven it to a cars'n'coffee and a Mopar club show. Aaannnd worked on it to fix the stuff that quit working while it sat and the stuff I broke while driving it.

So far I've kept it stock, as it starts right up and runs smooth. But I still want to have a fast-enough-to-be-fun street/strip car. I'm considering rebuilding this 318 with big-valve heads and a 4-barrel, or finding an LA 360, or even springing for a Magnum-based 408 from Blueprint. From what I understand, anything stronger than a rebuilt 318 will be too much for the 904 and 7-1/4. So a 727 and... an 8-3/4? A Dana 60?

I'll be doing almost all of this myself. Dad and I used to work on cars together, but he's 89 now and doesn't have the strength. He does still watch me work and ask a lot of questions.
 
Engine is up to you. The 904 is plenty strong enough.
I have friends that race in E stock,F stock running in the 10's with 904's.
Other than Valve bodies and converters they run stock internals.
Yes the 7 1/4 will eat spider gears doing peg leg burnouts. To me the rear should be the first to spend money on.
There ya go,my 2 cents !
 

Nice looking car!
As said, the 904 will be just fine.
As for the rear, make darn sure it's a 7.25- with a 318 there's a 50/50 chance it's an 8.25, and that is plenty stout for a cruiser/weekend warrior.
Don't feel too obligated to start tearing into a good running 318- you'd be shocked with the improvements a set of decent rear gears and a little looser torque convertor can make; and you'll retain the rock-solid reliability of the 'teener. Keep in mind, the time you have to spend futzing around on it (because someone told you that's what you HAVE to do) is time you could have spent driving it!
 
Only reason my 904 blew up after my 318 rebuild is we didn’t connect the lockdown linkage. Agreed, double check to see if it’s an 8.25 out back first.
 
re the rear end, it's common to swap in a ford explorer 8.8. they come with (mostly) 3.73 gears, lsd, 31 spline axle shafts and disc brakes. remove the 'long' side axle and cut the casing down 2 7/8", then fit a second 'short' side axle. this gives the total width almost exactly 'A' body size. parts are much cheaper than a mopar 8 3/4 due to the popularity of the 8.8 in mustangs.
neil.
ps lots on here about this swap if you look.
 
I always ask my self this question: What percentage of my time do I want to work on a car or drive a car as is. Best of all worlds is be able to keep driving the car as you work on it.
Like said above, you can wake up somewhat that you already have for cheap ish.
Teeners last forever...until they die.... as in any motor!

Is that a different lug spacing from the A-body?
 
Nice car. Glad you decided to keep it and good luck with it! I have a 74 myself that has been off the road since around 2016 or so. Keeping it a running driving project is my only advice lol
