Has anyone attempted or (hopefully) completed this swap?
I have a 1990 GMC 1500 RCSB. It had a 350/700r4. I recently pulled the 350 and purchased a complete 6.0 LQ4 with DBC throttle body. I previously purchased an LS carb set up so my plan is to get it running on the carb initially, and switch to EFI later. Below are the parts I have purchased:
- 6.0 LQ4 with 168k miles, plan to change the rear main seal and oil pump before installing it, cam or other performance upgrades to wait until later
- ls carb intake (unbranded, bought used)
- Edelbrock Performer Carburetor #1406 600 CFM With Electric Choke (Non-EGR)
- Edelbrock Universal Micro Electric Fuel Pump - 38 GPH / 144 LPH (Gasoline/E85)
- MSD 6014 LS Ignition Controller
- Jegs GM LS Engine Swap Headers for 1967-1999 GM Pickup Trucks, Part Number: 555-30069
- Jegs Heavy-Duty SFI Flexplate for 1997-2016 GM LS1, LS2, LS6 Series Engines
- Jegs GM LS Crankshaft Spacer, Adapts: GM LS1, LS2, LS3, LS6, LS7, L92 To: Pre-1997 TH350, TH400, 700-R4, 4L60, 4L60E, 4L85E
- Jegs Fuel Pressure Regulator for Supercharged and Turbocharged Carbureted Engines [1.5-25 PSI Outlet Pressure]
- ICT Billet Swap Engine Conversion Mount Kit Compatible with 2WD 1988-1998 Chevy OBS Truck
- ICT Billet - Solid Aluminum Transmission Mount
I have a few more things I need to get before attempting the swap. The mounts I chose are not adjustable but are supposed to put the engine in stock position to mount to trans. I will need to buy a tv bracket for the carb and get some fuel hoses. I planed to attach to the factory fuel lines with some steel clamps to hold the hoses on. I dont plan to use the Edlebrock fuel pump, but it came with the carb set up I bought off marketplace.
I need to learn what to do with the factory wiring and what's possible as far as gauges and such. I know I'll need my factory harness from the 90 gmc to run the fuel pump but other than that I'm lost. I think the MSD will take care of a lot of it but not everything I'm sure.
Any advice or guidance is welcomed. I've never attempted this level of automotive work before. I generally just jump into stuff and learn along the way but would greatly appreciate anything that could help move the process along quicker.
Final note, I recognize all the benefits of EFI. However, I am this deep in parts and plan to use the carb set up to get going.
Thanks in advance.
