    Cold weather warm up times.

    My 85 would fast idle for about 3 minutes when it was below freezing, I would let it idle down before I drove away, It seems that the engines I've had that I've idled long periods always smoked bad when you drove them away afterwards, Grog 85

    Instrument Cluster With Desirable Tachometer Disassembled Inside (Important News!)

    I did take a tach from a 1990 dash and modified it to work in my 85 dash panel, Had to grind a little and drill three holes, and it worked great, I used the 1990 tach and the 1985 faceplate, I used the tach sensor from the 1990, everything plugged in and worked with the dash grid...

    Brought home a new truck

    With a couple mods, those M motors run pretty good. A little more compression, a little more cam, and dual exhaust, they're a respectable runner.

    A/C clutch

    Can anyone tell me if the a/c clutch is supposed to be engaged in the heat or defrost position? Ive got a 2001 F-150 with the 5.4, and really don't have any heat. The engine warms up good, 195 degrees. I spent 5 questionable hours tearing the dash apart to check the temp blend door, and all is...

    How much weight off the back bumper?

    One thing to remember is as you add weight 8 ft. behind the rear axle, you are taking weight off of the front axle. If your rear tires are rated to 6100 lbs., and the GVW is 9200, with that 800 lbs hanging 8' back there, you might be pushing the limit of the tires. I'd do as was mentioned, and...

    Look what I get to do for my B-Day

    I may be wrong, but when I was asking the same questions about the cdr a couple of years ago, I was told that there was only about one pound of pressure on the cdr spring, so it should be easy enough to blow through. I honestly never tried giving it mouth-to-mouth though.

    6.9 rebuild time

    On the high-compression side of it,I've never heard of anyone running more than 22:1 (I may be wrong). But I know of one Cummins running 21:1 with 80 psi making 890 hp, I know its a whole different animal, but with studs and a good gasket an IDI should be able to hold up reliably under more...
