    Squishy brakes

    when bleeding the brakes, are you using the combo valve centering tool, it keeps the valve centered when bleeding the brakes. it may shift one side causing a brake issue. what rear caliper did you use, are the brake nipples not pointed up when they are installed? maybe look into hydroboost...

    In Search of Original Brake Lines 81-87 C10 Power Disc Brakes

    hope yours turns out better than the other 2 companies I tried, I wish I could put em on blast, but it would take to much effort to dig up the email/invoice... both kits were returned and refunded. I bought one from summit racing and another vendor directly. Trash flares (burrs inside) and the...

    R12 recharge from high side?

    when you charge the car, it should be inverted anyway, where the hose that is feeding the car or a/c machine is on the bottom. Car off, it doesn't matter that much, you can charge from the high side, low side, both at the same time if you want. Default on the r-134a Robinair machine is charge...

    Lower steering shaft

    From what I remember taking mine apart, no, it will not just slide in / out. To replace it you would need to disassemble the column 100%. that shaft is similar to the intermediate shaft that connects the column to the gear box. assembled and set with plastic to make it solid, yet can collapse if...

    About to ruin one of the nicest C3500's with an Ls.. Pictures

    checkout coldhose.com adapters they have a few adapters and I'm sure one of the 3 will work. If you have the oem hoses, they can probably be repurposed.. I wound up re-purposing the L83 suction hose and discharge lines by adding new tubing and tube nut to it and had a hydraulic shop that does...

    LS Fuel Pressure

    100%, if you plug the vent up, you ultimately will starve the engine of fuel even if the tank has fuel.... it can also deform the fuel tank if the vacuum is strong enough. Buddy built a chevelle ls swap and the vacuum deformed his tank.

    LS Fuel Pressure

    Humm.. I had a slightly larger aftermarket intake tube and factory mass airflow and that made mybswap run rich. I wound up putting a wideband on it and tuning the airflow sensor table.

    Power Door Lock Issue (and fix)

    terrible advice on the solution part ... I would recommend against using the power lock actuator to free the seized component! The door lock actuator is not designed to overcome seized components, which increases current which can burn up both switch and actuator... and then your left wondering...

    LS Fuel Pump

    stock tbi system pressure is like 14 psi? that sounds like that would be a restriction. If you woud be using an internal pump, mine as well get one to do the whole job? stock pump for stock builds work just fine for the stock sending unit wiring. I ran just that for about 10 years on my 87 with...

    LS Fuel Pump

    I designed these fuel hats for the c-10 for higher current rated fuel pumps. the stock sending unit terminals can only handle 14 amps... more higher powered pumps draw more. while uncle eddy never has a problem. data sheets led me down this path this setup allows up to 25 amps on fuel pump power...
