We need just a bit more info. Budget, use of the finished car, etc,etc would be helpful. If I were starting from scratch, I'd do an LSx swap. But that's just me and I've got too much invested in my SBC swap.

Olds 403 or 350 is a direct bolt-in. 455 is only slightly more work.
It is harsh, but I agree!!
Whether from a performance angle (the Olds has a better block) or from a budget angle ( the car is already set up for an Olds V8) you're better off with an Olds V8.
We do need to know your true intentions so that we know how to advise further.

It may be true that a sbc is like a butthole in that everybody has one but building an Olds 307 over one ehh I don't know that even I am that sick of seeing them. :lol:
Depends on your goals. Usually from where you are at an Olds 350/403 is the easiest best swap. An sbc is also cheap and commonly available. But the cool thing about a Gbody is that you can put in just about anything. Heck as you can see from my sig and in my pics I put a 500 Cadillac in a Cutty. Why because I got one for free from a derby guy. Turned out better than I expected.

Don't know about where you are, but in my area 455s are fairly cheap and readily available. If my car had a 307 that's what I'd be looking for.
There is nothing wrong with a Chevy swap! However, it is much more involved that using an Olds 350 or 403. What to use depends on what you intend to do with the car when it is finished, what is available where you live, what parts you may have laying around and personal preference. Other than that, there is not much more I can really say. The biggest negative to the Olds is that the Olds 350 has not been in common use since some time in the 80's, while the Chevy was used up until the end of the 90's in the full size vans and trucks. You can still buy a complete, new Chevy right down to the block for a reasonable amount of money, not so much with the Olds. The Chevy also has inexpensive heads with modern chambers available from 96+ truck applications while that is not so with the Olds. However, the Olds will physically bolt in your car using everything you have on the 307, and used parts may be available cheaper due to lower demand. Olds engines also have a high nickel engine block which Chevy engines largely lack. This means that it will have good ring seal for far longer than the Chevy. The cost benefit analysis of the whole thing comes down to how you intend to use the car. As a mild driver with a pump gas engine not intended to run nitrous and running mostly stock components, the offset of having to buy all the brackets and some accessories to put in the Chevy will offset the higher parts cost of the Olds. This assumes a horsepower level of around 320-350. If building a highly modified engine, the Chevy will be cheaper. If you know people who are heavily in to either engine and have stores of used parts, that too can be an offsetting factor in what you decide to do. The same goes for your personal knowledge of a given engine family.
