Default Fuel filter adequate

I have been looking for figures on what the stock fuel filter on my '85 will flow, more so, how much horsepower is too much for it?

IMO not necessarily a HP requirement, rather a gpm requirement. How much fuel must pass through the filter to satisfy the engine requirements.

Sorry, I don't know the limits on the fuel filter but it should at least be equal to whatever your fuel pump can push through it.

Most likely your GM filter flows more than you need - but only way to really know is to have a FPG attached to rail that you can read at WOT - period !!!!! Fuel pressure drop(s) can be seen on my website - OK ?

Thanks to all, I can cross the filter off my list of possible culprits. I may have found my problem today so I will wait and see, if not then I will describe the issue.
