oil pan question
Sirs,
I am building a new 305 for my 86 Pontiac LG4 s/e. What high capacity oil pans successfully work on this chassis? I am going to a high volume oil pump, due to the 224 duration cam that I am using, so I can rev this engine a little.

Re: oil pan question
True. The stock pan and oil pump are more than up to the task. If you want to add something to the oiling system, the "Z28" oil pump by-pass spring will bring the oil pressure up a little.
A "high volume" pump could invite other problems.
There are other oil pump mods than can be done but the OEM system gets the job done up to a few hundred HP and RPM over stock.
For the record, as I had anticipated some road racing/auto x , I went with a Canton baffled extra capacity oil pan with the appropriate oil pump pickup. Stock GM pump with the above mentioned spring.

Re: oil pan question
Like Skinny Z mentioned, standard volume high pressure "Z28" pump is all that's needed. Stock pan has adequate capacity but needs extra baffling, even for straight line acceleration. Canton stock appearing pans are what I use. I've had fitment, leak issues with Moroso oil pans.
