Kinda short and terse, but okay.
Will the shock valving - designed for a 3- lb car - be correct for your build?
If they're based on Ford, Chrysler, or any import mfg, they're unacceptable?
And define "cheap"

If you want to learn more, please visit our website custom coil springs for cars.
SkinnyG, a long-term member & builder here, did a set of DIY coilovers once upon a time. You can find references to them on his build site - http://www.gwellwood.com/project-cars/the-lethal-locost/lethal-suspension/
He was away from the board for a time, but he's back now. I'm sure if you contact him he'll be happy to give you sage advice. He's a very sociable & helpful guy!

I’ve since made enough changes that I broke down and ordered AFCO sleeve kits ($180US), and proper size/rate 1-7/8″ ($180) springs, and I’m sure it’s not over yet.
The next one will be much better….
The problem is using sealed OEM shocks intended for far heavier cars; the valving will be way too stiff in a much lighter car, plus it locks you into using a given stroke. One way to cheat is to purposely design the car with an installation ratio such that the shocks "see" loads which require OEM spring rates. Doing that though designs in all sorts of compromises that aren't really desirable. If there's one thing on the car where you get what you pay for, it's shocks, but there you go.

I'd have to agree with KB58 - as the coilovers are so overwhelmingly important, not only to the car's handling qualities but to the very safety of its operation, I wouldn't be tempted to go cheap there. It's kind of like building a high-performance car (which we all are, really) and equipping it with old, used, dried-up tires. It's just not a good idea, IMHO.
We went so far as to have our GAZ shocks custom-made in the UK for our specific needs. Yes, it's costly, one of the single most-expensive items in the build along with the custom-made Weber carbs, but there are things you can scrimp on, and things you just shouldn't.
This is not to say it can't be done, of course. It has been done, I believe, but the amount of experimentation required would probably cost nearly as much in the end as reasonable-cost, ready made items suited to your build.
If you're looking to save money on coilovers, you might consider visiting your local Harley shop. In my experience, many of these shops get customers who want their brand-new bikes customized before they even take delivery, resulting in these shops having piles of brand new, take-off parts like shocks, mufflers, etc. which no one wants to buy for their Harleys. The rear shocks off the rear of a Harley, designed to cope with an all-up weight of - lbs., might be a good start.
Just sayin'...

Southwest Speed sells a grooving tool for $60 that will put the right grooves for round wire lock rings into twin-tube shocks. Or you can make a similar tool from a Harbor Freight pipe cutter if you have access to a lathe. Southwest has the spring mounts, caps, and bits at reasonable prices.
Early VW Beetle rear shocks have an eye on each end; after you cut the sheet metal guard off the top, they're suitable for Locost purposes.
Damping rate and ratios change by manufacturer and product line; there's no real way to tell what you're going to wind up with until you try it. But for a street car you can do a lot of experimenting for less than the price of one racing shock.

*cough* You rang?
My Locost was completed in , has clocked over 20,000km's, driven down to Vancouver and back three times (about 900km round-trip), autocrossed both locally and at the Provincial level including the Canadian National Autoslalom Championship. It's been my daily, has driven in sun, rain, AND snow, and has proven itself to be a very acceptable suspension setup.
I chose Corvette rear shocks for the front, as they used about the same spring rates as I was using. The valving is VERY good. I chose Chevy Sprint rear shocks for the rear, as they used about the same spring rate as I was using. The valving is VERY good. The car is very composed and handles very well. The secret is to pick shocks in applications that were designed for about the same spring rates you will be using.
Having said all that....
Would I do it again? No.
You're not really saving all that much money, really, once you add proper threaded collars and spring mounts. And proper shocks would probably safer ones, because the Monroe and Gabriel shocks I am using are not really designed to support the weight of a car.
My NEXT locost (currently hanging from the ceiling to get it out of the way for now) will use something proper, not cheaped out as I did. AFCO is good, QA1 is good, KONI is good. There are others. Just contact them and tell them what you're doing, and see what they recommend.

Is this the time to ask about motorcycle coilovers?

The OP specified Chevy shocks for some reason and doesn't seem to have visited since.
Regarding bike shocks, it all comes down to the installation ratio and whether they give enough stroke.

Contact us to discuss your requirements of custom lowering springs. Our experienced sales team can help you identify the options that best suit your needs.
I made my fronts using the 75 corvette shocks but used two piece locking collars for the base of the spring to sit on. Just clamp it loosely over the shock and then slide it down to the weld ring and it will never move.
