Re: C% vette LS1 to 69 Camaro how much can I use
I think... engine (and all accessories), ecu and wiring, radiator. ABS would be a real pain, so your call there. There are a lot of aftermarket LS conversion wire/ecu setups, all work well, so you may not really need the factory harness... just keep them around during the project just in case.
Kore3 makes a lot of kits so you may be able to keep most all of the brakes and transfer them over. Give them a call, let them know what you have and they will be able to fill in the missing pieces.
I believe Corvette utilizes a dual fuel tank system, so that won't work. There are quite a few ls1 threads... some here, some on other forums. For my LS project, I have purchased a tank system from Tanks Inc... good pricing, products and customer support. There are other options too... just look around.
Lastly...keep the Corvette around as long as you can... there are a lot of odds and ends that can be used from the donor car.
