I am looking to replace the engine in a '58. The car is beautiful, but I am looking to drive it, not show it. I'd like to hear some recommendations from current C1 owners. What are the best replacement options on the market today?
There are a lot of different models of crate motors. I was looking for some recommendations from people who have put them in. What size engine pairs best? Are they happy with them?

Then the field is up to what you're wanting for your driving enjoyment.
So, back to you. What are your driving wants and needs? Blazing power but with marginal street manners, easy cruising? High speed cruising (gears matter?). What kind of transmission do you want/need/have/want to keep? Interested in any modifications to squeeze in anything other than a small block Chevy? Gas mileage matter? What about plug and play maintenance? Want to set it and forget it like modern engines?
This^^^. Best bang for the buck. You can do the swap in a weekend and be driving again right away. I would go with a 383 or a 406. I am running a home-built old school 383 in my '61 and it runs much stronger than a 350 and does it at lower RPMs. I used a '68 big journal 302/327 block with the road draft tube vent so I can still run the stock valve covers and it looks exactly like the original 283. If I were in your shoes, I'd go crate. A friend has a Skip White 427 cid (small block stroker) that he's very happy with. It was costly, though.
I am not looking for blazing power. Not planning to race or impress the neighborhood with a show of force. But its got to be responsive. I am buying this to drive, not show, so looking for reliability and low maintenance. It's got a four speed manual trans, which I plan to keep for now. I live in horse country outside of Nashville so mostly driving two lane roads into town. But I want to be able to drive it on the interstate without being passed by a Prius.
Beware my friend, "Crate does not guarantee Great". As mentioned above, Get a GM with a GOOD warrantee.
GM has some great deals. A guy I know with a '63 coupe bought one of those budget GM 290 HP crate 350's. I drove the car and was amazed at the power. The engine was smooth and strong....and felt much better than the advertised HP rating. Great bang-for-the-buck.

I have used one of those also, (long block) and was very impressed with the power (56 Chevy)
See Karl Chevy or Scoggind-Dickey there are many more so check price
The amount of HP is directly proportional to the amount of $$$ spent!

Careful. If you go with a 383 or larger motor with significantly more torque and more power than what was ever envisioned for your stock drive train you may need to upgrade your transmission and rear differential to take all that new power. You could have your existing motor rebuilt this winter and with a nice roller hydraulic cam and aftermarket EFI have a really nice reliable driver.

A garden-variety 383 with 420 HP or less will be just fine with the stock trans and diff. My '61 has had a 383 in it and has been driven HARD for the past 35+ years. The guy before me really beat on it. I drive like an old man compared to him. The same transmission and rear end used in the '58-'62 Corvettes were used in the 409 full size cars. No worries.

I'm not gettin' in to the replacement recommendations but I'll say this. The engine you have is about the poorest example of SBC power that was made. Almost anything would be an upgrade.
Too bad GM aint selling those 1200 crates anymore they are now 1000 more. You can beat it to death and if you blow it so what?
I am sure GM is going to want an authorized installer (dealer) doing it to keep the warrantee.
There goes the "budget" engine replacement! lol
Dont see why a guy couldnt put some decent mounts, Ujoints in and be reliable unless one drives like a complete meathead. Most failures out there are the driver/installers fault.
