Until you understand what everything does and how it works I would leave it be. After you understand everything better, THEN you'll know what to remove and what you need to keep. That's my advice.

Ok, couple of things, and I'm gonna probably sound like a dick, but I'm not trying to.
1. if it was stock, leave everything alone. No point in doing anything besided replacing what may be broken or missing.
2. The oldsmobile 350 stopped being produced in 1980, so if your car has that engine in it, it was swapped in.
3. In stock form, your car either had a Th200c (three speed, P R N D 2 1), or a Th200r4, a 4 speed OD (4th), D (3rd), 2, 1. Look under the car. If the pan is shaped like a square with a corner cut off and has a little dongle on the passenger side with a metal line running to it near the back where the driveshaft slips in, it's a th350.
4. NO G BODY EVER CAME WITH A BIG BLOCK OR Th400 TRANSMISSION. EVER. No special order cars, no rare cars, nothing. Only ever got small blocks, v6, (inline 6 in some countries), that's it. Whoever told you that they did, don't listen to them anymore.
5. A 350 oldsmobile (and for that matter Buick too) ARE SMALL BLOCKS. The 455 olds (again, buick as well. i mention them because people seem to think the same about buick v8s), are BIG BLOCKS. They share very little in common with their small block brethren. With the olds, yes you can swap heads around with minimal machine work. But that is by coincidence, not design.
6. Since it seems like your engine has been swapped already, all the stuff was probably already done. Post your engine casting number, and some pictures. For all we know, it could be a 350 olds swapped in place of the 307 it most likely had.

I am sorry if I made a misunderstanding I thought my transmission was a th350 and I have confirmed it is the original 307 and the transmission is stock as well it is th200c I did some number searching while I had some daylight left my car is a stock cutlass supreme
And also no worries you're educating a classic car noob this is my first classic car
So, yeah. imo don't bother messing with anything. if it's stock stock, it will still have all the computer stuff. you'd spend more money that you would want to for little to no gain, all you'd be doing is loosing mpg and cash. save up, buy a 350 olds and a good th350 or a 200r4 if you want overdrive, and plop that in eventually. keep the old engine and trans around, if you ever sell the car take out the 350 put the 307 back in.
That's my plan in the first place I want to do my research before i do anything like that and also money is tight for me right now plus it just got the carb rebuilt
just keep it in good tune. replace any broken vacuum lines and fittings, change spark plugs and or wires if necessary, check timing, change fluids as needed, just basic maintenece. you can tuck stuff out of the way, but no need to elimiate stuff that would hurt "performance" and fuel economy if missing.
My father has a 330 and a turbo 350 from his 65 cutlass hes swapping for a year correct 400 big block and a turbo 400 from a another newer model is the 330 and the transmission viable for me down the road for when I'm ready to take such a project on?
idk much about a 330 olds ina g body, but if it's anything architecturally like the 350 olds it shouldn't be a hard swap.
You and I seem to be sailing similar boats..
My 86 GP is stock, 59k miles. 305, 4bbl, 200-R4 4 Speed Auto, 7.5" Open rear.
My issue is that there is absolutely nothing wrong with the drivetrain (except the distinct lack of power) and it runs fantastic.. so why not run it?
I got a Edelbrock Intake with a EGR Port to retain the fully functioning "Computer" set-up.. Headers and duals are going on it.. and thats all Im going to do.. just run it. No real reason not to. Im not dumping money in the 305 for power, as the return on investment just isn't there. If I do something for power, its going to be a drivetrain swap/replace.. Still on the fence about what I would do, but Ill cross that bridge if/when I get there (350/383/LQ4-9 Swap).
But, as stated, if your goal is simply sound.. just get headers and duals.
