Default Fuel pump question

I'm getting ready to buy a new fuel pump for my 81. My car has a 3789817 (engine code) 327. So, when looking for a fuel pump, are the 350 fuel pumps the same as the one for the old small journal 327s? Also, any suggestions on fuel pumps? Gonna stay mechanical.

different pumps were used for different applications but they all will fit a 327 or a 350. Is the engine stock or modified? If modified what has been done? Depending on your answer you can go with a stock replacement pump or look at after market performance pumps.

Thanks for the info. I actually don't know a lot about this engine, just bought the car about a month ago and the guy lied about what was in it. He said it was a 350 stroked to a 383, but after buying it and finding the engine code, it's a 327.
Here's what I know about it so far:
Aftermarket cam (can tell by how it runs: https://drive.google.com/file/d/1DJF...ew?usp=sharing)
Aftermarket rockers
Edelbrock 1407 carb with Torker 2 intake
Crankshaft either has a bolt hole drilled or is aftermarket (since they didn't come with bolt holes and it has one)
882 heads (gross, I know)

I wouldn't bother throwing a lot of money at hi-po aftermarket parts for that engine. Any OEM replacement fuel pump will due for you.

If you intend to continue using the Vapor Canister, then you will need another 3-Port fuel pump. A little bit harder to find and a few less choices, but do-able.
I think Airtech has one and maybe Carter, Delco?

It is possible to build a 383 out of a 327 IF it is a large journal 327. It could be why your crankshaft has bolt hole.
