I am undecided on a 350 or a 383 in an 86 z28 with a 305 tpi that was converted to 4 bbl holley carb.
I am worried about getting an engine that needs too many mods to just get it running. I want to build it up as I learn how but I would like to have someone drop one in for under $3k. Any suggestions?

First, welcome aboard thirdgen.org.

Now, I moved this from the thread where you posted it because it had nothing to do with the subject of that thread. The rules to which you agreed when you signed on clearly state that you keep posts on-topic in the threads in which you post. And, before you post a new topic, a is recommended.

We're willing to help, but following these simple rules helps maintain order on the Board.

Now, as to your questions, getting an engine and having it installed for $3000 isn't very likely unless it's a used engine or plain-jane replacement. That being said, a basic performance 350 swap isn't going to require a lot of changes to get it running or keep it running.

If one of your objectives is to learn to build up an engine, I have to say paying someone to install a different engine first is a step backwards toward realizing that objective.

I dont really have the time to put an engine in, nor do I have the experience. I figured I would have a bottom of the line one put in and just add on to it. I just got the car though so I want to drive it right away. If i try to put an engine in it myself, it will take all summer.
I have been reading up on everything and it seems like a 350 is an easy fix but I want a little more torque.
A 383 has it but I dont know if it will nickel and dime me swapping everything to get this to work.
Can I keep whats on my 305 and just drop a 383 in its place or will I be looking at a lot more than just buying a long block?

A lot of what you're trying to accomplish, and the order in which you accomplish it depends a lot on how much you're willing to spend on it.

Externally, a 383 (being the 350 block) is identical to the 305. If it bolts to the 305 block, it bolts to the 350 block.

My suggestion to many who want the experience of assembling an engine, without all the effort is to buy a shortblock, which is basically the block and rotating assembly. For beginners, that's the "hardest" part. All the measuring and precision involved. If you want the experience of doing it all, then I would say buy a rotating assembly kit that's pre-balanced and then get your block, have it done up and put it in yourself.

I like shortblock routes. You don't have to worry about the assembly process of the rotating assembly, which is the most time consuming process of building an engine (filing rings, checking all the bearing clearances, crankshaft thrust, side clearances, etc etc). But you still get the advantage of picking what heads and cam you want and being able to install them yourself.

If you're not looking to burn someones doors off with massive power figures, an entry level shortblock, basic aftermarket iron casting heads, and a pretty good cam goes a long ways.

Thanks for the advice. I think I would be better off having someone put the engine in for me since i dont have a cherry picker, motor mount, torque wrenches, etc. over time i will get what I need but i think i'll start out easy. The bad thing is i dont know anybody in this state that could help when i screw something up.
i'll take pics of what happens.


i hear that the 383 is great off the line but unless you have high end gooodies on it, your hp dies out around 4k rpms. Would a turbo help that?

That's an inaccurate characterization. A 383 will act in a manner consistent with the cam, heads, induction, and exhaust you have in/on it. A 383 can make great torque down low and good power up high if the combination is right.
