      I have a 425 in a 66 buick. Do you have a part # for this application. The last set of headers I had to modify to fit. Can you email me a cost as well? In Canada.

        The set shown on the new products page is designed to swap a newer LS-styled engine into early GM F-body and A-body cars.
        While they will bolt to your engine they would likely have interference issues with other components under your hood. Flowmaster does make a set of Scavenger Headers specifically for your application, however they are a “Short-Styled” header.
        If your looking for a set of long tube headers, I would check out the offerings from Dynatech, Flowtech, Kooks and PaceSetter, to name a few.
        Depending on what you plan to do with your ride… Short tube headers will deliver more power in the low to mid RPM range (where most of us drive), while Long tube headers will give you better performance in the mid to high RPM ranges. Which header is best, depends on what your needs are.
        Thanks for the question and best of luck with your project.

        I haven’t owned a truck, but 12 mpg seems about right depending on how you drive. With those tires it is prlbbaoy less! It all depends on what you want. For $3000, I’m sure you can find much newer trucks with possibly less miles. Check out the market before you commit to a purchase. Remember gas might go way up again, and I would start to question the reliability of a 1985 model, so there may be hidden costs in the future. Going back ten years is a big difference, just keep this in mind.Would a bed box/cover be a better idea for storage?
