    My Flat Tappet Cam Wiped Out So I Decided To Go Roller

    A little background: About 4 years ago, my '88 C1500 with the 5.7L TBI engine started overheating on me. I found the head gaskets blown. I knew the swirl port heads and peanut cam were about useless so, I decided to "upgrade" to better parts while trying to keep it fairly cheap - yeah right...

    Is anyone interested in participating, or going to see, Dino's Git Down? Here's the flyer with details and more links on their website. Friday sounds like fun with ONLY 1938 - 1998 Chevy and GMC trucks! IDK if I'll put my truck in the show lot, or park nearby and walk in. I missed it last...

    Steering Column Cover for Gear Shift Indicator?

    I looked back in this forum to 12/31/20 and didn't find a similar thread so, here goes... I'm sure, a lot of you have the issue where your gear shift indicator (auto trans) either doesn't work or is way off. This seems to be because the slot in the cover is worn out and the indicator cable has...

    PS request - 1500 Emblem on my door?

    Has anyone put their Bow Tie 1500 emblem on the door above the bump (trim) strip? What does it look like? I'm thinking maybe just above the body line the same distance as the bump strip is below it? The new emblems I have don't go on the bump strip so, I'm thinking of places to put them.

    Side Molding and Trim After Painting or Not?

    I'm thinking of taking that step to get my truck painted. To do it right I need to remove the side molding, wheel well trim, front and rear bumpers, the tonneau cover and bed rails caps I just installed, yada yada yada. Since the bumpers are worn and/or bent and the side molding and front...

    ECM, Chips, Moates Burn 2, etc

    I have some stuff that's been laying around for a couple years which I'll probably never use again. 1 - 1227747 ECM with a ZIF (Zero Insertion Force) socket that uses the SST 27SF512 flash chips (I paid $135 about 2-1/2 years ago). 5 - Blank SST 27SF512 flash chips (Moates wants $9 ea) 1 -...

    Electrical Upgrade? Just do it!

    I was looking under the hood of my truck and decided the Mickey Mouse wiring I did for my sub woofer and A/C compressor coil looked like crap. If I wanted to do a "4 Hi" mod or add something else, it'd get even more congested. You can see here the way I tapped the in-line fuses and mounted the...

    A 2"/4" Drop of a Different Kind

    I think I wanna do a 2/4 drop on my 88 C1500. The PO did some weird things to it so, I'm not sure what I'll get with what stuff. Let me show what I've got. I measured wheel well chrome to top of tires with a level and tape measure. Here's the front. And the rear. So a 2/4 drop will give...

    Swapping the Clutch on an R4 A/C Compressor

    The other day when I was waiting for curb side delivery at Total Wine my A/C started blowing warmer to the point it was cooler than the vent but not cool enough to keep me from sweating. It got a little cooler when driving home on the freeway then, when I got off at my exit it started blowing...

    My 88 C1500 "The Go-Get-Mobile"

    I bought my 88 Silverado in the spring of 2002 when my son was getting ready to graduate High School in Los Banos CA. At the time I was working in Merced about 24 miles one way. After living in LB 12 years I asked my wife "what's keeping us here anymore" so, we decided to move to Merced. I...

    Door Alignment and Wind Noise on my 88 Silverado

    For the 18+ years I've owned my 88 C1500 it's always had some wind noise coming from the passenger's side door. I was just looking at the rubber weather stripping on both doors and they all look good. Then I noticed the passenger's side was high as apposed to the B pillar. If I had slop in...

    Lunch Box Locker for my 10 bolt rear end?

    I've been thinking about getting a lunch box locker rather than a limited slip or a G80 grenade after some research online. I have an 88 C1500 Silverado with a 5.7L which, if I had to guess, is probably putting out somewhere around 350HP, with a stage 2 (600HP rated) 700r4 and a 2300-2500RPM...

    Welders, Welding Accessories, Projects - everything about welding

    When working on building/modifying our trucks, some folks have to heat, cut, and/or weld stuff. I thought some of you would want to show off your work and/or tools used. It's was probably 20 years ago I bought this Curv-O-Mark (Sticker says $65), I used it mostly for welding 4" - 12" steel...

    How does the AC system work in early OBS models?

    I've been searching for answers on how the AC system works in my 88 C1500 Silverado. Some places I read newer models that have the "re-circulation" button will open the door by the blower motor to get more cab air (when the AC is turned on), however FWIU the earlier models, like mine, by...

    WBO2 Sensor Wiring to EBL Flash II

    I bought the EBL Flash II from Dynamic EFI for my 88 C1500 Silverado 5.7L. In reading all information I can about it, I can get it to learn in VE (Volumetric Efficiency) tables and, with a Wide Base O2 sensor it will learn in PE (WOT) also. I'm trying to figure out how to wire the WB to the...

    HiWay Lean Cruise settings?

    I enabled HLC on my 88 C1500 (7747 bin) and have been running it a while. It seems to be working well, no knocks detected while cruising. I haven't messed with AFR or Spark. I haven't checked my mileage yet but will start on my next tank. The 1st screen shot is in scalars, the 2nd is in...

    My 700r4 may be FUBAR

    I bought my 88 C1500 in 2002 from a guy who managed a transmission shop. He said he rebuilt the tranny and recently put in a shift kit and a GM factory long block 5.7 (made in Mexico). Last year it started overheating so, after removing the heads I found 2 spots where it was bypassing through...
