Default Fuel Pressure ?

Just about done w/ the car, will the stock FPR be enough for the car w/ 36 lb injectors? I have about 43 psi with the key on. Mods are in my sig. Thanks.

Should be ok. I have an adjustable Accel on my Z and I have it set to 43.5 psi with the vaccuum line off.

Absolutely, it will be fine. You should have two settings: First, check at idle. It should be around 40 psi, give or take. Then remove the vacuum line (this simulates WOT). It should jump about 4 psi.
I run a stock unit with my Walbro 255 lph and 42# injectors, with absolutely no problems whatsoever.

Thanks, I had an adjustable FPR but it went south on me, so I just wanted to be sure, this is my first run in with an LT1 and so far it has been quite the experience. Just wanted to say thanks to all that helped.

Have you rented a fuel pressure checker yet?

I actually purchased one before I tore everything down, just to get the starting point. It is about 40 with the vacuum line on.
