Stand alone fuel management

[Slick68]

I'm throwing this out to get some ideas, opinions, and make a decision one way or another.

I currently have a carbureted LS1 in my 68 C10. The carbed setup utilizes an MSD ignition control box to fire the coil packs based off the cam sensor and crank sensors. I'm considering making a switch to EFI within a year or so. Most will tell me to just use a factory ECM/PCM and electronics, which I don't really have a problem with. It's most certainly a tried and true system with many benefits.

Here's what I want to know, though. MSD offers a harness (http://msdignition.com/product.aspx?id=4701&terms=6010) that allows use of an EFI system, but still allows timing controls without entering an ECM/PCM, which should allow the use of a stand alone fuel management system. The problem is I don't know enough about EFI and which system is best, and which one I should look into for doing this. Also, is there any major advantages of doing this over the factory EFI system?

Your best bet is to sell the MSD box and and add a stock manifold and related EFI items, including a stock ECU. If you have a carbed LS1 now, I would add a LS6 intake and throttle body. I bet you will gain 30-40 lb/ft of torque on the low end.

That's probably the route I'll take. I'll most likely use the Edelbrock intake, though since I have my coil packs relocated to the back of the engine.
