    1987 TBI tach install

    Should be a couple places in the fuse panel labeled "ign" to tap. Or use a relay and tap into anything that gets power with ign turned to ON.

    that should not matter too much as long as it is an ign power source.

    31x10.5 with 3:73 gears.700R4 trans. What RPM will I have at 70MPH?

    I have 33x10.5 (spec is 32.5in, probably actually 32in, or a little less rolling diameter), 3.73 ratio, and a 700r4. my RPM at 70mph is about 1950rpm and at 75mph is about 2100rpm for flat land cruising. Using the grimjeeper calculator, 31in tires (rolling diameter might be 30.5in?), the rpms...

    1987 sbc long block valve cover oil cap

    Pretty sure that's how my 1990 suburban is also. Just screws on to the valve cover.

    No power to A/C compressor

    The compressor won't start cycling until it gets some refrigerant in to close the low pressure switch. Check for 12v on the harness going to the low pressure cutoff switch. If you have power there, start charging. It might take a can or so before the pressure gets high enough to close the switch...

    No resistance in reverse, drive feels like I'm pushing against the brakes

    i think it's much easier to pull against the e brake in reverse compared to going forward.

    ALDLDroid on an android device and a Bluetooth ALDL cable from 1320 electronics is what I use to have nearly all the capability of a scan tool. you can monitor almost everything the computer sees.

    Vehicle shutoff while driving

    the way it is cutting off like that makes me think something in the ignition. make sure the distributor cap isn't cracked, plug wires aren't touching any sensor or ICM harness wires, look for arcing at night and/or mist it down with water to see if anything is arcing, etc.

    hei distributor

    Carrying a spare module, that takes a screwdriver and 15min to change, is a lot different than carrying a spare fuel pump that normally requires dropping the tank. I carry fluids, some basic tools, and easy to repair, likely to break parts - module, cap, rotor, rad hoses, relays for my...

    Windshield washer motor questions
