    I'm new to the site and would like some information on the Police Special 428. I have a 1966 Ford that was ordered out by the Missouri Highway Patrol and has a 428. On a couple of TV programs I have heard Carroll Shelby say he used these engines in Cobra's? Is this true and what are they worth? Thanks

    Cliff,

    The 1966 Shelbys were all small blocks. The 1967 GT 500s used the 428 Police Interceptor motors. Your engine would be suitable only for a replacement ( not dated correctly). Do you have a dual quad intake?

    Thank you for your response and information. No I don't have the dual quads, this is a single four barrel engine.
    Could you tell me where I might find the date code? Thanks

    Between the oil filter and the pan facing down

    The aluminum intake and carbs are the money parts

    Thanks again. I'll take a look and see what I have. I've been familiar with this car and am sure it's all original so the money may be a restored Missouri Highway Patrol car. It only has 100,000 and the engine has never been apart. Thanks

    Yes the 428 police engine (PI for short) was used (or substituted) in some of the BB Cobras instead of the 427. The 427 was in short supply and much more expensive when compared to the lower horsepower and less expensive 428 PI.The Cobra is not to be confused with the Mustang based GT350 or GT500. The Cobra name was only associated with the 2 seater aluminum bodied Cobra up until after the end of the 67 model year. You will not find too many 427 Cobra owners admitting that the 428PI engine was the original engine in their car opposed to the race bred 427 however.

    Thanks Bob, that is sort of along the lines of what I had found on a car program that featured Carroll Shelby and the Cobra's. So my dilemma is whether to sell the motor to a Cobra enthusiast or restore the 66 Ford 500 as a true Missouri Highway Patrol car with original drive train.
