What is YGM? Thanks for the pics. I can at leat tell where the rad hoses go, and I know where all the accessories are located now. I probably won't have my motor in my hands for a week or so as it is being shipped from Cali. How long did it take you to get your truck up and running?
I came up with another question. What to do for AC lines?
YGM = You've Got Mail
A/C hoses will have to be custom built. You'll want a high head pressure cutoff switch welded inline, also.
As I've stated before, go LS1 if you can find someone to buy your LT1. Street rodders love them. You'll have far less headaches with an LS1 type engine.
It took me three weeks to convert mine and I did all the work myself except burning the custom chip.
Okay, coming down off my high-horse.

The LT1 is about the only thing I can do. The parents are already disappointed that I built a 383 stroker for the truck and made to much compression and too much cam to get enough fuel to it through stock FI. So now I have to sell that. We figured we would just got LT1. It's a 4x4 truck so if I were to go LS1 I'd probablt have to get a transfer case too. They'd be pissed if I wanted to sell the LT setup for a LS. I'm not worried about it, it will be a good setup hopefully. The LT1 in my Trans Am is great. Don't get me wrong, I'd like to use a LS1. It's just not an option right now.
I want to get my truck running with this LT1 in it by Thanksgiving. Is this an impossible goal? Keep in mind I may not have it for another days.
First thing you will need is a chip for the PCM with the VATS disabled. If it has OBD 1 you'll need that. Contact Street and Performance and they'll fill you in on the details(www.hotrodlane.cc). When evaluating the wire harness, connect orange wires to hot all time connections and pink wires to switched 12v connections. Black or black with white stripes will be grounds. Tee in your factory oil pressure guage into the LT1 fitting. The OBS water temp sensor screws right into the head. You'll need a high volume/high pressure pump. I used the 93 Corvette stock pump in mine. Be sure you use hose made for fuel injection to connect the pump to the intake steel hose and use stainless steel hose clamps on the hose in the tank. If you don't get the factory fuel hoses on the engine you'll have to get you some quick connects at the auto part store. One is 5/16" and the other is 3/8".
You'll have to go through your factory harness and graft it to the LT1 unless you buy a Painless or S&P harness.
Done by Thanksgiving? Maybe, but I doubt it. If you have no job and nothing but time, maybe.
FWIW, in TX you can't put an older engine in a vehicle and expect to pass vehicle inspections. Only same year and newer. I'd check with your local laws before attempting the transplant or you'll be doing it again.

Do you think a Painless harness would be 100% plug and play, or do you think there would still be some small hurdles? How hard is it to graph two harnesses together? I don't have a job, and I do school on the internet (senior in high school). So I got time. I just wish I had the stuff so I could get started at it. I can't do anything right now I guess. I kind of doubt I will have it done in time for Thanksgiving... it sure would be nice though. I will have it mounted by then for sure. The wiring will probably be what holds me back.
See the previous post about inspection legality before going any further. You do want to drive it don't you?
Can you take your stroker pistons out and have them cut to reduce compression or just buy you a set of pistons made for low compression 383s that are used in turbo and blower applications?

I talked to the garage I normally get my vehicles inspected at and it is OK as long as I have the same emissions equipment (EGR, cats, etc.). I could do that, but I just want to get away from the Vortec spider injection system. I already bought the LT1, I have to stick to it.
Sounds like time to get wrenching, then. If you want it done by Turkey day you're going to have to hustle. You might want to have S&P send you a DVD of how to do the conversion. You may be able to do without it but it couldn't hurt. I have a friend that we put my old LT1 into his 90 C1500. I'll see if he wants to help you out with any other information. While waiting for the engine, you can swap fuel pumps and pull the old engine or are you driving it with the 383 in there right now?

I'm driving it right now, but I could swap fuel pumps. Would a fuel pump from a LT1 F body work? Could you by chance get me a link to that DVD? Thanks
