i think the real question is how are you going to supply fuel to the carb?

It may be best to look for another engine.

It would be awsome to use a mechanical fuel pump but i know the provision may not be there as well as the cam lobe missing. If i was to keep the injectors it might be cheaper to buy the fuel tank out of the suburban as well. If i go carb then a 50$ holley in line pump will work i thought. ?

Well, putting an electric in line will work, but it may or may not be simple; Where/how are you going to mount it? You will also most probably need a pressure regulator. What about return line?

Top things to do when buying a used motor to drop in.

Do you have a vacuum guage to carry with you? At least check the vaccum on the engine. Here is an article with a chart of vacuum readings and indications of engine condition. You can print out the chart and take with you to do the checks. Technical Articles: Engine testing with a Vacuum Gauge - at Greg's Engine & Machine

drop it in and leave it alone..
dad knows best..
sealing up the top end with a fresh valve job will make those 179k rings show just how worn they really are..
leave it alone!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Okay looks like ive found a decent running vortec with 178,000 for 300 bucks... I can hook a vacuum gauge to any vacuum port on the manifold for a check correct? Lookls like its leaking alittle oil from the timing cover. The guy sais he hasent done anything to the motor, hasent even really done a tune up he sais. It has the original plugs in it. scary :/

Just a thought (and maybe a dumb idea full of holes).

If the Vortec 350 is running, I assume it has a good fuel injection system and computer. Have you considered putting the complete fuel injected Vortec in your truck? It may be simpler than going through all the changes you need to get a Vortec working with a carburetor. And it will probably run as reliably as a stock engine.

You will need to figure out a fuel pump that works, and you will need a VSS and O2 sensors to feed the computer. The rest of the sensors should be on the engine. I'm also not sure how the computer would work with a non-computer transmission, but there should be a solution.

Why haven't you called your local machine shop or tech school to see if they might have a 350 shortblock or longblock sitting in a bag somewhere for a few dollars? I walked in the machine shop to visit my friend who works there and they had a rebuilt 350tbi motor sitting on a skid that the owner had walked away from and never came back. Keith said he'd be glad to get $700 for it if the guy helped him load it in his truck. People seem to think if its not on craigslist or e-bay it doesn't exist.

We have a newspaper here called The Swapsheet. Its a dollar and basically its an analog version of Craigslist; without the hookers. The nice thing about this is you find parts in there, advertised by the oldtimers (or their widows) who aren't computer savvy and they don't fall prey to the e-bay inflation. I got a rear decklid (with hatchback window), both headlights with motors, a door and both front fenders for a 1985 Firebird formula for $75. I sold the window alone for $125 cash. Parts belonged to some guy who left them in his moms basement for 10yrs

Funny you say that... I havent been able to find a motor I like yet so i stopped by the machine shop and local automotive trade school today. No luck for me.

Ive found alot of deals with tranny included for 1200-1500

I have my brand newly rebuilt reverse pattern manual TH400 waiting for the engine I buy. Thinking of selling it to add to my budget.. Since I started looking ive saved alittle more cash and now have 1000.

Trying to figure out how much i can sell my 400 for, I need to pull the pan and check valve body brand. lol it has 140$ worth of fluid alone. 45 minutes on it before I threw the rod.

Im really just a very simple (and cheap) guy. I've always owned carbed chevy's. At 22 years old maybe I SHOULD be looking for the next best "super chip".. nah..

If it was going to be cheaper to go the injected route i would but most the engines i see dont come with the comp and I would need pretty pricey fuel pump and maybe different tank. Looks like it would be about the same price and work either way. I would def gain MPg with injecters but i can work on a carb.
