    AIR Injection needed for 88 K1500

    I happened to be looking at the LMC Truck catalog today and they had the AIR hoses, check valves and oem exhaust manifolds. I didn't look for the actuator or the pump but they might have those too. I got a pump from O'Reilly's 6 months ago. They're all made by Cardone so get yours from...

    Ignition control module

    Circling back to the 9c1 police pursuit spec ICM (D1943A) the Delco OEM one is $115 at O'Reillys and $75 from Amazon. EDIT- RockAuto has a Standard Motor brand one for about $20 + shipping. Standard Motor is good brand. Off topic, the 9C1 police spec TBI injectors, which flow at 68...

    '88 5.7 Super Chip superchip?

    I've got the original ad and it is the same chip for 1500/2500/3500. The motor and tranny was the difference between the chips. I'll see if I can post a pic of the ad for posterity.

    '88 5.7 Super Chip superchip?

    I emailed Holley and here is their response: __________________________________________________ Thank you for contacting SuperChips! We do apologize, but there is no way for us to tell what is on the chip as any related equipment has been out of production for over 20 years. If the product...

    air pump/smog pump delete

    Thanks for the info about the diverter and ECM. I think the AIR system was a state regulation not a federal one. Some states, like California, inspect to ensure what the vehicle came with is there. Many do not. My state is one that doesn't but I'm going to keep everything intact in case I...

    '88 5.7 Super Chip superchip?

    My truck is a '88 5.7 K1500. Today at the treasure yard I stumbled across an '88 C2500 5.7 and the ECU had a "Superchip" sticker on it. The chip in the ECU had a superchip sticker on it too. In the glove box the previous owner had saved the magazine ad for the ADS Super Chip stapled to the...

    '88 5.7 Roller cam conversion

    Thanks! I saw a similar kit with cam etc.. from Comp. Plus they've got just the spider, dogbones and retainer in a kit by itself for $150 that you linked to. I read in one of the posts or maybe it was a footnote to the comp cam kit about that different retainer plate. I'll get the casting...

    '88 5.7 Roller cam conversion

    My '88 5.7 has the bosses for the roller cam spider in the intake valley. So I'm assuming a cam retainer plate can be installed but haven't visually verified that. I've read many of the cam threads here. I use the truck to tow a boat or trailer and haul materials. I'd like to not have to...

    Disable automatic lock?

    Thanks for the insights and help. I really appreciate this community. Good to know that it wasn't a factory option. I thought it was a little early for that. I didn't get any remotes with the truck. I'll look around for a box to figure out what is doing this. I've been under the dash quite...

    Disable automatic lock?

    In my '88 K1500 Silverado, if I the truck is running when you close the door it locks automatically. Usually if I have to step out of the truck while its running I remember to leave a window down or not close the door. However, sometimes I forget and end up locked out. Not such a big deal...

    Upgrades for longevity

    I'd start off by "baselining" the truck. Go over whatever records you have and start checking and repairing everything. Start with safety items. Eg. Brakes. How much pad/shoe is left. How much rotor or drum is there. When was the fluid last changed? How old are the brake lines/cables...

    Belt Squeak is driving me crazy

    My '88 had a squeak I couldn't solve with a belt or tensioner. Turned out to be AIR pump.

    Valve Stem Seals Differences

    Good point. You could remove the rocker arms first and then pressurize the cylinder and then remove the springs before changing the seals.
