Complete rebuild?

I purchased a Vortec 350 with 60K. This was a good running engine but the previous owner removed the heads, lifters and oil pan and then left it sit on an engine stand for three years after he lost interest in his project. This may sound dumb but could this motor be cleaned up and used or would a rebuild now be recommended. It isn't rusted up or anything and was stored indoors. Anyone ever use an engine similar to this before. Any and all suggestions appreciated.

If it was kept dry and it isnt rusted then I dont see why you couldnt. I have assembled some engines that have been stored properly but taken apart years prior with no negative results. Just check it out real good. Make sure the bore is clean and doesnt have any deep scratches. I think you will be fine.

if it's already apart, why wouldn't you rebuild it?

at the very least tear it down and check it out, throw some fresh bearings and new gaskets at it if everything looks good. otherwise you are just inviting trouble down the road.

also, how do you know it was good runner if you got the engine in pieces?

Everything appears to be good. I'm not looking to short-cut anything but don't want to waste money on a rebuild if it's not necessary. It doesn't have a ton of miles on it. I'm not convinced yet that I'm going to be happy with a 350 in this truck but I havn't driven it yet because I purchased it with a blown engine. It's a 2500 4x4 suburban it's replacing another 2500 4x4 suburban that was totaled in an accident two years ago. My other truck had a 454. I'm yet to be convinced it will have the towing power I'm looking for. The truck was such a good deal I couldn't pass it up. The guy I purchased the engine from had no reason to lie and seemed very honest. What would be the best way to re-lubricate this engine?

i just wonder why, if the motor ran great why he would pull it apart?

just put some SAE30 in a squirt can and let it have it.. that's what I used when I built my engine (in the places I didn't use assembly lube)

He wanted to build it into a 383 but when gas hit $4 a gallon he sold the truck. I would like to do the same with this engine but won't spend the money on it till I've gotten to drive this truck. Ever bought a car/truck with a bad engine only to find out when your done all the other issues it has that the owner just failed to mention? I want to be sure before I put too much money into it. I'll clean and oil it up and let you know what happens.

I don't know if you are going to like having 100 lbs ft of less torque than the 454.

But the gas mileage will be a little better.

Some of the trailers I haul can be quite heavy. I used a 91 suburban for a while that was only a 350 it seemed to do just OK. I guess only time will tell. I'm tempted to just have the 383 built but better gas mileage would sure be nice.

A well built small block can give you plenty of power and torque- but its not free. I'd rebuild what you have, 60k can do some wear and its been sitting apart for 3 years. You can do it the right way the first time or enjoy building it a second time. A basic ring, gaskets, and bearing kit is cheap.

That's right, and you pay for horse power but it's worth it. I don't think I'll know what to do with a truck that gets over 10mpg. (most likely over work it)

I've decided to do a rebuild on it , as long as it is apart I'm going to freshen it up. I'd rather not have to take it out again I have enough other projects to finish. Then if I don't like it at least a fresh engine will be a selling point.

Good call, condensation can form between the bearings and journals of the crank and pit the journals, so a strip-down and check of everything is definitely recommended.
