LS1 Going into a 92 Truck

[Injected1]

Ok, I am thinking about putting an LS1 in my 92 4.3 Full size....I understand the dificulty of this swap, I am just looking for resources on headers, wiring harness ect...anyone wanna offer up some resources?

You came to the right place. There are alot of guys who can help here. If you search some of the threads I think someone just finished that conversion and has an entire write up on it.

there should be a sticky in this section listing out 99% of the parts youll need for a v6/v8 conversion. check it out and post back if you have any more questions.

Yeah, got a little hasty with the question asking, I am mainly looking for somewhere to do the wiring harness because I loathe chasing wires

[LS1GMCTruck]

Street & Performance for their headers(G-Body), SpearTech for the harness & computer re-programing, motor mounts you can fabricate yourself from template patterns offered on LS1Tech.com, or buy them from S & P also. Air Conditioning compressor can be relocated to passenger side high position via a new Sanden compressor & mounting brackets from S & P, which made life REAL easy. Install all Vette accessories on the drivers side. 99' Corvette fuel filter/regulator combo unit in-line with electric fuel pump from tank. Standard late model F-Body dual electric fans with your 4.3 Litre stock radiator (or an upgraded version). Hope this gets you started...Gar

Thanks, let me tack this question on there...is it worth it to do the M6 swap if my truck is an auto? I love driving a manual, but I dont know how I would like it in a truck, I guess the question becomes 1 has anyone done it, 2 is the headache worth the gains?

Damn, sounds like someone read my recipe book for cooking up an LS1 into a 92 C1500. Other than the fact that you can use the entire f-body accessories except the a/c compressor which gets located up high on the passenger side with brackets and idlers from S&P or March. Wiring can come from S&P, too. NelsonPerformance.com for a basic tune and delete of unused emission BS, get the 2002 PCM and tune for a more aggressive performer.

So you have a guide to doing this swap somewhere? I could use it, if you wanna let me know where it is, Someone needs to prove to me this isnt an easy swap...

That was just a phrase. There are quite a few of us that have done that conversion though. If you have any questions just ask. You are at the number one source for answers for the LS1 into a 92 C1500, LS1TRUCK.COM!

LS1Nica just finished the exact conversion you are contemplating. DocGreen did a Vortec into an OBS that is factory quality. I did one but don't have the truck right now, it was stolen last month. Allen, farmtruc, did one in his OBS and has it turbo'd with an STS kit. GMCwantsLS1 has one in his pre-88 truck. There is a wealth of knowledge here to get you going.

Peanut .... there are many different ways you can do the swap. It all depends on how you want it to perform, what you want to have in the end, and how much intigration you're planning on having. If you just want a straight up haul a$$ machine it's not very difficult. If you're wanting everything to work as it did in the original configuration then it takes more time, finess, and $$$ lol . Feel free to check my site out there are a lot of pics there on my swap. I don't have a stepp by step "how to" on it but you can probably get some ideas. I'm fixing to get started on a 92 swap myself here in the near future. So post up your ??'s hopefully I can answer them or someone else will be able to help you.
