Re: Big Block Conversion
My car was orinially a SB and now it has a 427. I ripped all the old original wiring out (save it for reference, you'll be glad you did) and I installed AAW (american Auto Wire), I think they call the series Factory Fit. Just tell them what options you have, BB, SB, console guages, warning lights, auto, 4spd etc and they'll set you up with the correct harness. Mine was an AC car also and now it's not and everything wired up perfectly. They have a great tech support also, helped me out alot. You can also look through Ricks First Gen catalog, they have a list of Factory Fit AAW harnesses and it tells you what options they are for.
