How does the car run? What are you going to do with the car daily driver occasional cruiser? If you have lots of bucks and nothing better to do with them I also will give my vote for new motor.
If what you got does the job and your happy spend a few bucks dressing up.

The car runs well after warming up and I drive it pretty much daily. I am thinking about putting a new exhuast system and intake manifold.... nothing big.

I really like the 383 with 200r4 trans. The torque curve is almost straight, ie plenty at any rpm. I only drive the car for fun and love crusing 70 at 2100rpm in od. Punch it and do 100 in just seconds. I just can't say enough about these strokers. The old 350 only had 50k miles but this motor really makes me smile big there is sooo much diference.

its all about $$$ figure out what you want to spend and go for it......$3K and you can build that engine you have to be a barn stormer or you can buy a crate motor for that...good luck...there are almow too many options....you need to come up with some boundaries to this proposition

If I had the money I'd be getting a 383 tomorrow. It's all about what you're willing to spend.

if you have something like a l48, swap the engine;

i have a 73, original l48 car, now a zz4 fastburn car.


i would buy a zz4 base engine and add the hot cam and heads; much cheaper than buying the zz4 fastburn engine.

For a nice driver I'd Tune-Port fuel inject your stock bottom end. Should give a noticable boost in power and mileage.

Im not looking for big hp right now, only about 250-300. and I would like to spend as little as possible. OH YA and i want it to look nice .
so would I rebuild the one i have and put some stuff on it or just buy a 383.... also, i dont have any idea on where to start so which one would cost less to have it done? although i do have a guy down the street that knows his stuff..

Why not buy a used 400 cube stock motor, build it and be ahead of the curve. Just a mild build would get you the horses you want with a very reliable almost stock engine. If you really want to get crazy, stroke the 400 and really get some bang for your buck! Just a thought.

If all you want is 250-300hp then Tuned-Port is right on the money. Visual appeal is awesome.

Before I pulled & stored my numbers matching L82 on my 79 and replaced it with a custom 355, I did a complete tuneup (timing, wires, plugs, distributor cap, etc), rebuilt the carb and replaced the EGR valve and vacuum triggers (not the correct name but they are those devices controlling vacuum based on engine temp and screw into the intake manifold). Just these few simple things made a tremendous performance improvement.

It was a while back so I don't remember exactly but was certainly less than $100 in total. Of course I don't mind getting my hands dirty and do the work myself.
