    Oil Pressure Drops After High RPM

    When you get to the knock stage pull 1 plug wire off at a time and put it back on and if the knock goes away on any of the cyl. well...not good. I use plug boot puller pliers for that. Indicates a rod bearing bad. Cam bearings also may be bad. A lot of oil pressure is maintained in them. My 2...

    Vintage Air Gen V (5) or replace existing compressor, etc., for 1987 R20 Suburban?

    I bought my compressor from Rock Auto for my 88 R20 454 GMB part # 9712214 and it works OK but would not buy one of those again. Someone on here a while back said that if you run a parallel flow condenser and a blue orifice it will work great. Dont know though. Looks like I have a neighbor here...

    Running Hot at Highway Speeds with A/C On

    Guess I could see that if the clutch was not allowing the fan to free flow enough air. Always learning.

    Running Hot at Highway Speeds with A/C On

    After 30MPH your fan clutch is useless. Also check your high side pressure at 2000 rpm. Excessive amount will cause higher temps. Should be 275 to 325 max on a hot day with low side around 30. My guess is a clogged lower part of the radiator if all the other checks out. Hope this helps.

    87' R10 TBI 350 shuts off when driving. HeLP

    Throw a fuel pump relay at it. Happened to me.

    454 spits out carb at 20% or so throttle at low speed

    Not sure of the guts of the edelbrock but I would start with 12 degrees on the timing and possible look at the intermediate circuit in the carb. Possibly move up a jet size if that is what is in it. Hope this helps.

    06 4L60E swap into my 88 V10

    The original TBI system has a speed sensor in the speedometer but I am running an Edelbrock pro-flo so will have to see what the controller setup is when I get it. I had the bell housing up on the motor so I know that fits and am now measuring flywheel differences. looks like I will have to run...

    06 4L60E swap into my 88 V10

    Has anyone here had any experience with installing a 4L60E 2piece trans into a 91 or earlier V10? I have a controller I just want to get more clear on the flywheel, torque converter, starter problems I may run into. The Trans is out of an 06 Avalanche. I am done with the TV system!

    Steering column guru’s, where does this spring go??

    I go in there just to take that annoying key alarm out. Camp a lot and the keys stay in the ignition and I dont have to listen to it any more! Ha!

    They be coming soon! Both my burbs now. It was the converter bolt by the way. Dont have to pull the big ass motor out!

    2 WD but I have a complete 4WD drive train in my back yard... It may just find its way under this 3/4 ton. Will leave the 14 bolt in the rear.

    454 engine

    Thanks to all. I can live with that. I did end up with the burb and will be making sure of the knocking noise before I go pulling the motor. I have had loose converter bolts fool me more than once! Best score of my life though on this body!

    454 engine

    Greetings all, Anyone here have any knowledge about what MPG I could expect from an 88 Suburban with a 454? It only has 34,000 original miles but the guy that owns it did not change the oil enough and pulled a large camper trailer and it has a knock which I determined to be a rod for sure. I...
