will the stock fuel pump support a 383 LE3 with 42lb injectors? Or do i need to get the 255.

Thanks Scott

 

wablro 255 is a must on any performance engine. they've even shown gains on cam only cars with older gm fuel pumps. it's a must have. easy to install as well

 

When I dynoed my 383/LE1/30 lb injectors/stock fuel pump, I had my fuel pressure tester taped to the windshield. As I went to WOT, I saw my fuel pressure decay from 46psi to 42psi. The injectors stayed at < 85%, and the AFR was a flat 12.5:1. A bigger fuel pump is my next mod.

 

yeah i a planning on doing it for sure but i want to at least get it running this weekend since i will not have the pump till next week. I am gonna hook up a gauge and watch it.
