I just bought a 427 sideoiler with high riser heads and a dual 4 intake. Along with the deal was 2 sets of medium riser heads and a mechanical fuel injection set up for high riser heads. I will be selling the extra heads and injection. I was building a 383W (yes 383 ford) for my 67 Mustang coupe witch I also will be selling. My question is does anyone here have a 427 in their 67/68 Mustang? I would like to install a overdrive auto but I don't think there are any options available. I am new to the FE world so any help would be appreciated.
