I bought a 1992 TPI Camaro that has the L98 engine stroked out to a 383. The difference is that it is all Vortec from the heads up with a BBK 58mm TB. The fuel pump has died and I am not sure which one to buy! Should I match the pump to the 1992 L98 engine or step up a year and go with the LT/LS pump? I think either pump will work but I am thinking the output pressure of the pump is higher on the LS/LT pump. I am running an adjustable fuel rail pressure regulator.

I am thinking the Granatelli GM722-2
or
Walbro GCA758-2
or
AC Delco EP241

From what I can tell, all pumps should fit my tank and sending unit but the Granatelli has the highest output pressure! What do you guys think?

Should I go about this differently and identify what the car is running for Injectors and match the pump to them? All I can see is that they are orange.

So, stick with the pumps listed for the 1992 (L98) or go with the pumps used on the newer LT/LS cars?????

THANKS in adavance!!

ADDED: Just identified my injectors and they seem quite small! AT 43.5 PSI the rated flow is only 210cc. I am thinking this engine must be pushing 400 HP+ at the crank and therefore I should be running around 360cc???? What do you guys think?
