Sounds like you're already most of the way there. You seem to be deciding on exactly what you want. There aren't a lot of options that you've left to choose from. Personally, I'd opt for IRS.. It helps a lot....but them I'm in competition for the iron butt award. The 427/428 question is pretty much a moot argruement. $$ is the biggest difference if you don't intend on racing the car. The side oiler is more expensive going in, and a lot more expensive if you need to replace anything down the road. The HP difference is negligable if you're not racing. They both clean up and dress up nicely. Matter of fact, if it's done right, you'd have to be an expert to tell them apart. The fuel system depends on how original you want to be. Twin 600CFM holleys look great on a BBF motor. Even a single 700CFM Holley looks killer. If you're not interested in looking original then go with FI. It's a lot more efficient and you'll probably get better mileage. As to the color, for my money, nothing is as impressive as a black Cobra with those little tiny chrome bumpers front and rear.
