Default lq4 headaches into Monte SS

OK, so I bought the lq4 and had it delivered to the shop, only to go down and talk to the guys and get confused. The swap is going into my 86 Monte, the engine is out of an 03 Escalade, transmission is out of an 02 I believe, but its got the right torque converter. Thats not what I'm worried about though, its everything else. Heres the situations.

First, its a, and forgive me if I don't use the right terminology, but it uses the gas pedal sensor instead of a cable? I didn't get the pedal, so should I just buy an intake and throttle body or should I buy a pedal? If I go pedal, what else will I need?

I've got the whole wiring harness, the stock one, and the brain box. I've heard everybody say that it should be worked over to make it a plug and play. Who does this and what do they need to know?


Hmmm...what else, fuel, what will I need for the whole system? I've heard get the Monte SS tanks that are from a 4.3, I've heard you can use your regular fuel tank, I've heard it all, I just need some answers before I dive any deeper into this biach....so any help you could give me, advice, things that can help, they'd all be greatly appreciated.

Also, I was told that I could swap the ls6 intake can the throttle body onto this, but then I would have to swap all the accessories? Where would I find all these?


Thanks a million guys

Fuel tank- You would be better off with a fuel tank from an injected car than your old one. Tanks from an injected Monte will have baffles around the pump and sending unit. This is to keep fuel from sloshing away from the pump when you turn a corner and have less than 1/4 tank. Get a fuel gauge sender for a 4.3 injected Monte and a Walbro 255 intank pump. You old tank will work, but not as good.

Throttle body- To use the drive by wire throttle body, you need the matching pedal and tac unit. Without these, it would probably be easier and cheaper to swap to a cable throttle body. Depending on what tranny you plan on using, a cable throttle body may be your only choice. If you use a tranny that requires a TV cable, then you will have to run a cable throttle body, so you will have a connection point for the TV cable.

Harness- Send the harness and PCM to Jesse, www.wait4meperformance.com ,and let him modify the harness and re-program the pcm for you. Just tell him everything about the car and your intended plans, as far daily driver, or strip car.
