As tittle says, just want to know if these are the right numbers for a 2002 5.7 ls1?
Its for a 383 n/a stroker motor i'm building, just want to know if there the right numbers and if EV1 is the right connector choice?

They will be used on a fast 102/102 setup and have the fast billet fuel rails, so have the 8 larger o'rings for the billet rails.

Part number: 0 280 155 968
42lb Bosch EV1 High Impedance Injector

Also which Walbro intank pump:
GSS341, 340 or 342 to use? or are they all the same?
From what iv read there the same but have just that one number different.

Thanks in advance.

 

From more searching Looks like should be ev6, the ones iv found say 42lbs/hr @43.5 psi (39lbs on gm models).
