    You don't even need it. I had problms with nu tach too and I just removed it. The cable going to the filter will connect directly to the distributor. My tach works great without it.

    Knocking/Pinging with my 84 CFI

    Your base timing might not be what you set it at. The harmonic damper was bad quality those years and it is not uncommon that the outer ring moves compared to the crank. On my 84 the TDC marking on the damper was 6 degrees off then I replaced it. No visible damage to it.

    Rear window drain kit. Do they work?

    I installed the kit and it works for me. You must drill thru two layers and install the hose. After the first layer you are inside the the the car behind the carpet. You don't want any water there. Going thru the second layer you are above the wheel and the water will drain to the ground. I...

    forged pistons

    The 1982 and 1984 Cross-Fire Corvettes also have the same TRW 464664 forged pistons as the 1985. The same pistons were also used in the some high hp stingrays.

    Anyone running straight cat converters on their C4???

    The cat is a good muffler. My Corvette is louder now with new mufflers and no cat then it was before with cat and rusted out mufflers.

    WinALDL version 1.09b

    Sorry, no ... This is a 160 baud scanner for the older GM ECM's. The 1986 Corvette got the newer faster 8192 baud ALDL data, but for backward compability with the digital dash the 160 baud data was kept. MPG data is transmitted to the digital dash using 160 baud. In 1990 with the new dash the...

    Replace ceasefire on 84

    Why do you want you remove EFI an use a carb? With the stock heads and cam you will not gain much HP and you will lose low end tourqe and driveability. The 1/4 mile times will probably not improve. A lot can be done with the Cross-Fire to improve performance. Have you seen this site...
