As far as brand there isn't that much difference, often they come from the same tanks at the distribution center. Some do put in different additives but the gas itself is the same.
When it comes to what octane rating, that's a different story. You haven't said anything about your engine so it's hard to say. Unless your 454 is a very low compression truck engine you probably want to run 93 octane. That will allow you to run your ignition timing advanced for better performance and fuel economy.

Be careful with the oil, again it depends on the engine. If it doesn't have a roller cam then you need an oil with a higher ZDDP level to protect the cam. Today's cars all have roller cams and most oils don't have enough ZDDP to protect against cam failure.
Gather all the info you can on your engine and post it. GM made millions of 454's over 40 years and they're not all the same. What ever info you have can help us help you.

I'm not saying there is no difference in gas from one brand to another. What is more important is the station. The tanks get water and crap in the bottom. That needs to be cleaned out on a regular basis or it will build up enough that the pumps start pulling it up. There is always some junk on the bottom, that's why the pump doesn't pull from the very bottom. If the station doesn't look like it's being maintained then the tanks probably aren't either.
Another thing to watch out for is buying gas while the tanks are being filled. When they dump the gas in the tanks it stirs up the crap on the bottom. Now most stations these days have filters at the pump but again if the station isn't maintained then the filters probably aren't maintained.

Royal Dutch Shell
Marathon Exxon/Mobil Shintech Valero Conoco/Phillips BP Murphy Oil Those refineries are all within 100 miles of me, and I may have forgotten a few.. They all make gasoline that has to pass rigorous testing by all sorts of bureaucratic regulating bodies...which also vary by state. I'm pretty sure that the EPA regulates on filling station pump filters being changed on a schedule.

All fuel is pretty much the same because there are only three manufactures refining fuel. The difference is what is added by the individual sellers that can make a difference like detergents, etc. If you are running aluminum heads and are under 10:1 mid grade could work depending on the overall timing/setup on your engine. Because of the 454 torque and the possibility it could be iron headed I would stick with premium just to be safe. I use premium because I like the extra octane and the cleaners in shell V-power. I also run STP every few months to get rid of water buildup.

I only run BP 93 in my car and there has not been a problem with the way it performs.

I merged your two threads into one here, so we can all see it together.
I'll support what Hank said, that the octane rating of the fuel your engine requires is specific to your engine. As with most other things in hot rodding, just enough is just right, but not enough or too much can/will hurt things. For the most part, the compression ratio dictates how much resistance to spontaneous combustion (octane rating) your fuel needs to have. You don't need synthetic oil, you just need a good quality oil with an acceptable level of zddp. Off the top of my head, summit racing's new hot rod oil, Valvoline VR1 racing oil, the Joe Gibbs oils, and the Red Line racing oil....they are good for engines with flat tappet cams.
