ok so im looking in to swaping my lo3 out of my 1990 firebird for an lt1 and im just wondering if any one could give me some names of dealers that make some of the helpful parts for doing the swap like the wirering harnes and what other rhings i would need?. i have been reading alot of the threads on here about it but im just not geting what they are talking about so im just wondering if any one could help?

 

wiring - check with pocket. I'm sure he's still getting tons of requests, but he's the man around here when it comes to wiring, lt1 or ls1. Hawk's also does some swap goodies as well, worth taking a look around.

these swaps can be quite involved, definitely not something for the faint of heart. just keep reading and chip away at it little by little, the results are always very rewarding

 

LT1s are easy. The two main subsystems you need to update are wiring and fuel. Shoot me a PM on the wiring or DIY like in this thread

Fuel is pretty easy. You need atleast a TPI pump. Walbro 255 is better, but a stock TPI pump will suffice (V8 flow and 43psi). Next, all LT1s use a feed and return so your stock lines can be reused, just bridge from the frame rail to the rails. I prefer to run braided AN6 from the tank forward. PNs and diagrams for that are posted in here

Mounts and exhaust can be reused from the SBC. All LT1 accy's fit in a 3rd gen. Only AC requires a K-member notch

 

I make a LTX AC hose kit.

A couple people used to make LTX fuel lines and/or power steering lines but they haven't been on this website for a while and I have tried contacting them in the past about PS lines but had no luck.
