hey thanks for all the help im gonna pic up a nice camera and start the build soon./ I bought a 69 Camaro also the other day so im moving things around. I have a question. I wanna put a ls motor in it maybe (maybe) if I do I want to use a f1-r procharger,now I know they make the harness for the ls motors but how would I retard the timing for boost. I use to build turbo mustangs and use like ms or aem.I only see a kit from jegs for the ls motors. does it have optional programming. any help would be appreciated. I wanna get this part figured out before I get in the middle of building it. thanks
