I got the stock wiring harness stripped and de-pinned the AC, emissions and auto trans stuff via lt1swap.com. I'm sending in my ECU tomorrow to Brendan for him to tune it. This was a DBW truck and I'm converting to DBC, so I need to add the Idle Air Control and Throttle Sensor Position sensors to the computer. LT1swaps.com has all this info and is a huge help in all of this.
Slowly collecting parts for Red. I'm waiting on some M10x1.5 long bolts from McMaster Carr so I can bolt up the engine to my stand. Then I'll swap out the oil pan and some other PM stuff (rear main, water pump gasket, etc).
Ordered over the past 3 weeks:
-GM Musclecar oil pan
-LS3 Camaro exhaust manifolds & ARP bolts
- EVAP solenoid block-off
-NFW1050 Flywheel, LS2 pilot bearing, ARP flywheel & pressure plate bolts (need to order a clutch kit)
-Russell 6AN fuel line, fittings, pump, etc for fuel setup
I found out my engine is in fact an L59 (flex fuel version of an LM7). Seems a lot of the early Suburban's came with these. Almost all flex-fuel trucks came with a Return fuel system, but mine is a returnless (has a vacuum referenced FPR at the rail). This creates some issues with me wanting to run the common Corvette regulator most people run. This allows you to only have to run one fuel line from the fuel rail to the regulator.
My options are:
-Ditch the corvette regulator completely and just run 2 lines to the tank (most likely)
-Switch fuel rails to a return rail setup
-Plug return at fuel rail (seen some people do this and say its fine, others say not advised)
I also found out I have flex-fuel injectors that flow 36.6lbs/hr. These injectors usually came on 2004-2006 flex fuel trucks, but I guess I got lucky. This is a good upgrade compared to the ~25lb/hr stock LM7 injectors. This is good if I want to do any power adders down the road...
I've also tracked down a 4x4 SM465 here on Mud via
@DangerNoodle. Just waiting to figure out shipping and price, so that is one less part to worry about. The only thing I'm missing now is the snout/adapter that bolts the Sm465 to the NP205.
