Need injector identification: Marine Vortec Array
Hi folks,
I'm looking to ID an injector set. This is a replacement injector array to upgrade the stock Vortec (ca. 1999 5.7L truck) injector poppet-style spider.
Anyways, looking for lb/hr ratings and pressure specification.
The injectors are Delphi Lucas 0937-1246B.
The part # for the array is 93441235.
This is going to be a pretty stout build 383, with good-flowing RHS heads. I'm going to do the tuning with the factory 99 Vortec PCM using TunerCat's OBD2 stuff.
If the injectors are inadequate (ie. 19# or something), I'm really hoping that there is an alternative part# for an array with higher rating (24-30#).
Many thanks,
-Craig

Check these threads out.
It's where I found info on changing injector wiring on vortec to vortec marine. These guys are converting the intakes to marine and using external injectors, and also using ramjet intakes on vortec wiring.
I'm starting a vortec truck setup with vortec 350, ramjet, 4l60e, sequential injection, and dual oxygen sensors, for a streetrod application. I was going to use TPI/Edelbrock tpi/vortec intake, but found the ramjet intake.

Hmm, everyone I talk to suggests that larger injectors to fit into this arrangement are not available. Everyone says go marine external injectors or just limit the RPM.
I'm now considering replacing the harness/regulator block with a pass-through modification block which will then go to a small sub-harness. Then modify the bungs and fab up some mini-rails to fit inside the manifold. If I can pull it off, it should be pretty trick. And I can use those old SVO 36# units everyone has lying around!
Will post back if it looks promising.

If you have some old SVO 36#'s laying around I would be interested. Look at this link for the conversion. I think this is really the way to go
