Quote:For the Mustang's 25th anniversary, Ford asked us for a powertrain proposal for a 25th anniversary edition. We started with a marine 351 engine and added the marine camshaft and put fuel injection on it. We gave it back to Ford and they said the performance was improved over the 5.0-liter but it wasn't enough. At the same time, we were working on the Thunderbird Turbo Coupe with the small Borg-Warner turbocharger. So I hung two turbochargers on the 351, one on each exhaust manifold. Ford said it was irresponsible. It was so fast you couldn't keep it in your lane if you stepped on the gas. The result was that they did something that did not have a powertrain feature for the 25th anniversary. The only car that I think was done correctly is here in our museum. It's a one of a kind.
