    88 5.7L backfiring through TBI

    This started out as an intermittent SES light with the engine occasionally stumbling under acceleration. The only code was 12. Now, the engine back fires though the TBI and has little to no power. Fuel pressure is good. Plug wires are fine. Cap and rotor look good. Had a spare ignition...

    Replacing valves in TBI 350 heads

    The valve seals in my '88 350 were shot. The engine puffed blue smoke on cold start-up. I decided to pull the heads and replace the seals. The valves are all straight and the guides do not have significant play. I mic'd 'em and they appear to be ok. Some of the intake valves appear to have...

    Refrigerant blowing out of AC compressor

    This is my week of weird stuff happening on the truck (88 C1500 5.7L). Saturday, the truck was idling in the driveway to test the new cooling fans and out of nowhere the compressor blew refrigerant out of the back. The entire AC system was replaced in May 2018. The pressures were set...

    Electric Cooling Fan Conversion

    I finally got tired of the noise and inefficiency of the mechanical fan on my 88 5.7L. The temp would rise sitting in Atlanta traffic. The clutch likely needed to be replaced but decided to switch to electric fans. This is my daily driver and it needs to be reliable. There are a number of...

    Thinner head gaskets on a 88 5.7L

    I plan to pull the heads on my 88 5.7L. They are original and need to be rebuilt. The valve seals are leaking. Rather than milling 0.10" off the heads to bump compression, I was thinking about using a thinner head gasket. The OEM replacement is 0.41" compressed. FelPro has a 0.25" gasket...

    Skip White Performance Distributor

    Another post on here mentioned the Skip White distributor. My 88 had the original distributor and the bearings were worn. It was wobbling. I decided to give it a try. So, far it has been great. The truck is basically stock and I was not looking for a high performance distributor. For $69...

    Complete loss of 12V power......

    88 C1500 5.7L 144K miles. I've only owned the truck a few weeks. It has been driven daily for the last two weeks. Yesterday, took my son the park. The truck was parked for an hour or so. Returned to start it and there was no power. Nothing worked. There was no response from turning the...

    88 C1500 5.7L white smoke in exhaust

    A friend of mine is basically giving me an 88 C1500 5.7L short bed standard cab. It has 143K miles and looks pretty good. The only problem is white smoke in the exhaust. As soon as the smoke started showing up 5 years ago he parked the truck and stopped driving it. Now, his wife wants it...
