am I going to need a fuel pump sorry this is kind of a lame question but I can't seem to answer it for myself.
Im wondering if im going to need a fuel pump when my cars back together.
I know my cars going to be flowing alot more air but I don't know when it becomes a problem for a stockish lt1 fuel system.
So heres the basics of whats going in my car.
355
trick flow 21 degree heads unported
226/360 .565/.565 111
ported lt1 intake
52mm tb
Aeromotive Fuel pressure regulator.
Gona spin it to about 6500 depends where the powers at after i get it on the dyno.
Should be all the relevant info, I still have stock injectors aswell.. I figure if need be some red tops will be fine.

Did they cut the access hole in the car? If so, I'd replace the pump for piece of mind. It won't take long.
Btw, you'll probably need injectors like you said. I'm seeing almost 110% DC from my stock injectors at 6300 rpm with just a cam. I'll be looking for some 30lb ones as well.

As long as the stocker is pushing good pressure you should be fine. I am pushing 400+ at the wheels with my stock pump. True I only have 45K on the motor but it feeds my SVO 30#ers just fine and pressure stayes constant.
