    Carb Adapter

    Thanks for the info. It is the original stock manifold so it is a dual plane manifold. Mostly just cruising around vehicle - not a daily driver

    Carb Adapter

    Gave up on tuning the quadrajet and bought an Edelbrock 1906 for my 1977 C15 with 350 engine. Looks like there are a couple of options available for the adapter to fit it to my stock spreadbore intake. Any recommendations or opinions?

    Hard starting after sitting for a few days

    I have the “hard starting after sitting a few days’ issue on my ‘77 GMC C15. I’ve read through several of the posts and gained a lot of good info but still having the issue. I’ve taken the windowed seat out and replaced it with one that isn’t, I’ve cleaned and put epoxy on the plugs, and made...

    Quadrajet Spacers

    Any recommendations on brand and type. If I read things right, there are a lot of different materials they’re made with.

    Quadrajet Spacers

    Running a 1977 C15 stock 350, 4 barrel quadrajet and having issues with heat soak. Considering a carb spacer, wondering if that’s an option and if so what recommendations anybody has. Thanks.

    Suddenly running rich

    I’m at a loss. I did a rebuild on the quadrajet, had it dialed in pretty good, ran it for a couple of weeks, and then a few days ago, it began to run rich at idle and off idle. The only thing I can say that has changed is the temperatures have gotten quite hot since about 5 days ago. I’m...

    Carb Opinion

    Last year i changed out the carb on my 1977 GMC C15 to an edelbrock and threw the Rochester Quadrajet on the shelf. While organizing the work space I ran across it and got the crazy idea to do a rebuild on it, having never torn into it before. I’d really welcome your thoughts on a good rebuild...

    TH 350 shift issues

    FYI - all the shift issues were corrected by installing a new governor. I torn the old one apart and it looks like when I had it at the the transmission shop they drill out the plastic gear to fit the retaining pin and there were some very small shavings that got down in the valve. I had checked...

    Wheel/Tire Opinion

    Decided to have the original rims blasted and powder coated white and use the original dog dish hubcaps. Sooooo, the next question is which tire - Cooper Cobra radial or BF Goodrich Radial? Interested to hear opinions.

    Progression Distributor

    Just wondering if anyone is running their 350 with the progression distributor with the Bluetooth file capabilities. I haven’t seen any recent updates on its reliability/durability. Thoughts?

    TH 350 shift issues

    thanks for the input. I’ve changed the vacuum modulator a couple of times and installed a new rigid line from the manifold to the modulator and measured the vacuum pressure at the manifold and the modulator and it read the same. I have not installed a vacuum gauge and driven it to see if...

    TH 350 shift issues

    Still having shift issues with TH350 that won’t shift 2nd-3rd when it‘s warmed up, usually 15-20 minutes of driving. I added a trans cooler and new vacuum modulator with no change. i’m about ready to buy a new governor just to see if that fixes the problem. I’ve given up on the shop that did...
