L92/L76 Fuel discussions

What are you guys running for fuel injectors, fuel pump, and fuel pressures for your L92 setups. What % duty cycle are you seeing?

I have a 402 LS2+ L92/L76 setup with just a mild cam, with 42# SVO injectors. I have big fuel rails and aeromotive FPR.l

I have not started the engine yet. What fuel pressure should I be running?

Thanks

im running a walbro 255 in tank, green tops with my little 370 and am seeing mid 60's at WOT. i have the proproducts fuel rails also. im at stock fuel pressure. why would you want to run at a differnt pressure than stock? 58 psi should be plenty with those 42lbs. you will prob be closer to 75% duty cycle max i would say.

I was using SVO 42s# which were a bit big so dropped back to 36s which run ~86%.. I use 42s on built LS7s and they are perfect there. I expect they will be the best for upcoming 441.
Probably too late but the 40s that come on the L92 seem to have considerable upside.
