350 w/ 290k on it is dying, tips on making it last a little longer?

My friends blazer has 290,000 miles on it, and its on its way out. Thing is, its his only car and he needs it to survive a few months longer before he can afford a new engine. Did plugs, wires, injectors, but that didnt help that much. Any sorta "tricks" to keep the thing running/maybe make it run a little better for a few thousand more miles? Thanks,
-Chris

How is it dying? It is knocking, severely underpowered, smoking badly, burning too much oil or any combination of the previously mentioned? I think if a small block went 290k miles you cant ask for much more, thats pretty darn good.

By the way, my dads 73 pickup has 255k on it's original 350, it smokes a bit on startup but it runs pretty well.

there is a product called RESTORE. It will help the rings and guides to seal better. I put some in a slant 6 with 200k and evened up the cylinder pressures.

It may help get a couple of K's on the engine.

Larry, be prepared for the "mechanic in a can" wisecracks but personally I swear by the stuff, I used to be a non-believer but a friend convinced me to give it a try. The stuff definitely makes a difference. It cut my oil consumption in half and I picked up a mile or 2 per gallon on my 150,000 mile 3.8 and an annoying little "tick" at idle went away.

I put a can of Restore in on an old '83 non-rebuilt 305 I put in a cheap '81 malibu wagon -

seems to have helped with a little oil burn I was getting... it's no powerhouse engine, but hey, it gets the job done.
