    Catalytic converter failure anomaly?

    Probably bent valve on 1 and 2 pull heads and take them to a machine shop and have them check the heads these trucks being fuel injected tend to not have bad cylinder walls in most cases so I don't think it is rings.

    Catalytic converter failure anomaly?

    Do a compression test on all cylinders, only way to tell if compression is the root of your problem. When changing plugs is the perfect time to do this test.

    I can cheat and use straps made of the seat belts in the yard, they allow you to use anything you can find in the yard other than the carts so I can carry alot of weight on my shoulders and use my legs not my arms. ;)

    The truck is a factory 70k 1990 454ss with a 3 speed th400 and a 14 bolt rear in 91 they put the 4l80e in but it was not a very good tranny in the first year so the tranny I would want is from a 94-95 it has a bad engine and has been parked for over 15 years but I would love to have overdrive.

    How To: LED Map Light Conversion (Overhead Console)

    Dash Kits Metra Double Din

    So how many of these have turned out good? I have a pioneer that I bought for a Ford that is itching to go in and I am pretty picky about the fit and finish when I put a product in my vehicles. I will custom paint so not worried about paint and texture but fitment. Thanks Brock
