ls376/480 or ls7
ls 376 is the best bang for the buck.
Honestly, I cannot imagine what my 69 would be like with the LS7 in it. It would be a real handful - I would not want to drive it with my foot in it. You'd be giving a lot away in chassis rigidity, handling, ABS brakes, and traction control with that combination, IMO. You'd sure have some bragging rights though.

First of all I agree with what you said. I have a 69 with a modded 427. Nothing crazy but probably close to 500 HP and it will definitely hold your attention. It's not as settled as the Z06 is for the reasons you stated.
You and I have a bit in common actually. My 69 was originally Riverside Gold. I also have a C6 Z06. And I have a Camaro that I've had since 1970. That's a nice history you have with your first Vette.
There is something about an LS7 in a C3. 500+hp and lightweight. But by the time you get done with the cost of the motor, sump system, fuel system, Computer and Harness, Gauge conversion, PUlley System, Rad/Fans, and other pieces to make it work. You are in pretty deep.
An LS376 is about 470hp?, considerably less but other then the sump system requires the same effort/cost pretty must to get it in.
You also have to consider your existing drivetrain, suspension, and brakes but that will also depend on how you plan to drive it.
In my case I bought a 15k mile LS6 short block for $1000 and dropped by own Stage 2 heads on it, 228/234, 588/592-114 Cam in it and a Maggie (Maggy is more for bling then go as I don't really beat on it too much). Cost of the engine without the Maggy was way less than a crate motor and left more money for bling.
So it depends on what you are looking for and what you want to accomplish.
