How much HP is stock L69 fuel pump good for?
I'm finishing my engine and was wondering if I need to upgrade the fuel pump. I'm going to be around 325-350hp...

You'll be fine, you can even opt for an aftermarket if you like. The mechanical pumps only should put out like 4-8 PSI for an N/A application. Otherwise you could flood your carb with more PSI.

It will probably keep up. If it seems like it isn't, you can pick up a carter street/strip pump for ~$40. Cheap insurance.
