    Load springs/Boost springs

    I've been researching rebuilding my 700R4/4L60 and came across an interesting theory on whether to use or not use the boost springs. His discussion starts at the 1:24:00 mark. I'm in agreeance with him that they should be used to prevent the clutches from dragging and burning when not applied...

    Leaking VSS

    Has anybody ever seen the sensor itself leak? About six weeks ago I checked my fluid and it was 1/2qt low so I crawled under there and found a drop of fluid hanging below the VSS,dry everywhere else. Went to NAPA and got a new VSS o-ring and changed it. Yesterday I was under there again taking...

    Jegs Headers

    I just received my Jeg's brand headers and I'll have to say I'm impressed so far. My research pointed to Schoenfeld making these for Jeg's. I have always bought Hedmans since the early 80's but I think those days are over. The first thing I look for is how much weld bead is obstructing the port...

    Code 32

    We see this one all the time and this morning Smoky throwed it. Had to take Annie to the vet for her rabies and distemper shots and on the way home on popped the SES light. Couldn't tell anything was wrong with the truck so I came on back to the house and did the quick check with the jumper...

    Fuel Quality!

    I been running Marathon gas for several years now until today. Yesterday my favorite fuel station had bags on all their pump nozzles so I had to go down the street to a Chevron station. Pumped in $40 worth and went home. This morning I had to go back into town and do some running around. I drive...

    Fuel Gauge Calibration

    This has been a topic of discussion many times on this and other sites so I want to share my technique for calibrating a new sender unit. The factory had a set amount of resistance in their senders that worked with the size of the tank and the gauge on the dash but once you install an...

    Micropack

    I have been trying to get the terminals out of a MicroPack 150 connector without destroying it and those little bassards refuse to come out. The connector I'm working with is the four terminal IAC connector for that 454 TB I'm rebuilding. I've got the little blade tool that is supposed to push...

    Scroll Compressor

    It's starting to warm up out there and it's time for me to think about replacing the A/C compressor in ol Smoky. I asked about R4 replacement scroll type compressors in someone else's thread and either didn't get a response or I can't remember what it was. Are they any good? Seems they would...

    Distributor Vents

    I was just reading another post about the rust and corrosion found inside a T400 distributor. When bought Smoky one of the first things that got replaced were the secondary ignition components and when I removed the cap I discovered the reluctor and pickup coil were seriously rusted up and the...

    Factory 5 Spoke Wheels

    Has anybody ever cut the small spokes out of the five spoke wheels? Would it make them too weak? I've seen aftermarket wheels with a lot less meat in the spokes then the factory wheels would have with the small spokes removed.

    MAP Sensor!

    Do any of you greybeards remember the MAP sensor that was attached to the air breather with the spring steel clip on the inside? I would like to use that style when I do the 7427 conversion on Smoky and get rid of the mounting brackets for both the MAP and ESC that won't be used for that ECM...

    Cruisin'

    Had to go out on a service call this morning. The air was cool and dense and ol Smoky was feeling his oats. It's amazing how well this worn out 305 runs. Had Creedence in the CD player,windows down and cruise set. I got the mans clock running and came the loooong way home. Was kinda bummed the...

    Battlebots

    I didn't know where to post a thread about this so I figure this was as good a place as any. Any of y'all get into Battlebots! I personally hate robots for the fact they've put way to many people out of work. My current profession is clockmaker and the German tallcase movements are all built by...

    Last Post!!!!

    Well folks, For the most part it has been a real pleasure to hang out with y'all but I was accused this morning of phishing on the first ride thread. I spent the first 20yrs of my life screwing up and the last 40 striving to be an honorable man and I'll be damned if I'm gonna have some self...

    Adjustable FPR

    When I bought ol Smoky one of first things I did was replace the fuel pump and filter. I've always tried to remove fuel filters without shaking them to much then after getting them off shaking the crap out of them and dumping them out through the inlet side to see how much crap is in them. Well...

    7747-7427 Swap

    Hey Folks. Anybody out there done a 7747-7427 ECM upgrade? I've got a 7427 coming to upgrade the ECM in ol Smoky and read the swap thread on the gearheadefi site. Everything looks pretty straight forward with he exception of the TCC pin. They're saying to use E11 to drive the TCC which is the...

    Shock Angle

    Can anybody tell why GM put such an angle on the rear shocks? I would think they would control bumps and rebounds better if they stood straighter up. Were they going for more travel?

    Electronic Caveman!!!

    Been awhile since I owned an electronically controlled engine(bout 22yrs) and I never did anything to those other than normal maintenance. Enter Smoky,my 91 C1500 SCSB with a very tired 305. Now ol Smoky is a nice solid truck but the motor is pretty close to toast. Been driving around with a tow...

    Not default of the defrost.

    All the doors in my climate control work fine and do what they are supposed to do but when I turn the climate control off the mode door goes to panel. All my old chevy's were either cable or vacuum operated and the default was always defrost in case there was loss of vacuum to the control panel...

    Staged Throttle Bodies

    Has anyone tried to do a staged dual TB setup? I was wondering if the drivers in the computer could run another set of injectors? The idea is to tee off the injector wires coming off the PCM to a second throttle body with a staged linkage like the Q-jet. The secondary TB would have a micro...

    Antiseize It!!!

    Well I fell into the last ditch! Years ago a local fisherman brought an Oldsmobile in my shop with a knocking 231 V6. He was hoping I could do something on the cheap just to make it last till run season when he could buy a new(better)car. I told him I had an idea that I had never tried that may...
