    1978 Cutlass 305 5.0 Timing

    Good evening, After some work has been put into the engine I was having issues getting the engine to turn over.

    Help! 305 Knock?

    Hey guys I have an old 305 in an 83 Malibu, I plan on pulling it and putting in a 350 over the winter so it's alright if it's toast. I've only been into the hobby for a few years and this is the first knock/noise I've had so I'm lost on what's causing it. Ran good all last year and used it as a...

    MONTE CARLO Possible 350 swap

    I am currently looking around for a small block 350 to switch out my current 305 with. My dad and I within the past 2 years put in a new carburetor, intake, headers and made the exhaust true dual instead of the factory Y pipe. How much of that would be compatible with a 350? It's also a T-top...

    GRAND PRIX Tach Help

    Hello all, I recently posted about some tach troubles. Well I have it all in the dash, mock jumper bar and everything. Signs of life, but no life. When ign is on, it jumps to zero, so I know it’s getting power. When I start the car, no rpm’s show up. I can tap the needle and it’ll go back to...

    EL CAMINO 350/290 swap from 305

    Hey everyone. Cam finally went flat in my original 305. I’ve been looking into the most amount of power I can get with still passing California smog. Looks like that fresh Chevrolet crate 350/290 is the way to go for me, it’s a daily driver but I take it to shows too. They come with a 222 cam...

    I've got fuel and spark... why won't she start?

    Hi All! I'm afraid I'm one of many to make my first post a cry for help. I'm at the end of my rope with our 84' Caprice Estate 305. The short story is, I rebuilt the Rochester Quadrajet meticulously, assuring everything was done right, and now she won't run. The car ran before the rebuild, but...

    The Lemange

    Yesterday was awesome! I Drug home my 1980 Pontiac lemans that I dubbed The Lemange. It was quite the experience. It was the first time I've hauled a car on a trailer, the first time using our car trailer, and I don't have a key for the car so we couldn't turn the wheels. It was an adventure...

    Coolant in cylinders

    So I pulled the heads off my 305 and there is rusty water/coolant in cylinders 1, 3, 5, 7, and 8. The gaskets look fine so it doesn't seem like it would have leaked throught the gaskets. What would cause this? Also when I took spark plug number 5 and 7 out a decent amount of water dumed out. Any...
