> Does anyone know the Stock fuel pressure setting on a 87 Iroc With a 305
TPI motor I put a adjustable fuel pressure Regulator on and it is running a
little Fat. I needed to increase the fuel pressure to compensate for the
increase from a 305 to a 327 but I bought the system in parts and I put the
Adjustable regulator on as I was putting it together and none of my manuals
gives a setting so I set it at about 50 PSI to start. Even some formulas for
calculating what it would be would be fine I have a Big Calculator ;)

stuff first, but any suggestions on what to add there also would be fine.
