So i just picked up an 80k mile L76 6.0L out a '08 Pontiac G8. All i got was a long block period. No accessories, manifolds, harness, etc. I'll be swaping it into my 1978 Malibu that im currently building. The only thing i know that im doing for sure is that i will be doing the DOD delete and a big cam.

Heres where im lost or just indecisive and where i could use your input. Im definitely going fuel injection but WHAT fuel injection im going to use is the question. So far its really only between two options: run the factory stuff with an LS3 intake/ECM/harness OR run a carbureted style single plane WITH Holley Terminator TBI EFI??? The only one im iffy on is the holley setup because I know what the factory setup is capable of running and doing with a stock ECM and a custom tune but i dont know if the holley setup would be less efficient, make less power, or even work with a big cam. Its the only TBI injected style between the FAST, MSD, Edelbrock, etc. that will allow additional laptop tune ability if needed. What donyou guys think? Stock or TBI? Any of you guys have any experience with the Holley Terminator system? They make a kind t thats plugNplay with the GM LS coils ans sensors etc.

You don't want TBI. Use GM intake and rails and get this:

Awesome thank you! Thats what i was trying to find but they have so many different part numbers for these damn things! So is this computer self learning like the terminator kits?

Yes, both systems use the HP ECU.

I like my Edelbrock Victor Jr intake with Edelbrock fuel rails, stock GM injectors and adapted for my stock LS1 throttle body. The car runs very well and solved my clearance problem in my little short under-hood area.
