Bagged 1969 C10 (new here & looking 4 help)
What's up guys?? New C10 owner here.. 23 year old from Myrtle Beach, South Carolina.
Coming to look at all of your cool trucks, but to also get some help. I normally mess with fords (own a 67 f100 & mustang).. so I'm having to teach myself the tricks and turns of Chevy stuff. 1969 C10 with a cammed 350 that has been bored over .40 backed with a 4 speed manual gearbox. This thing sounds mean. Love it!! But I have one small problem. Only happens when I try to keep a steady speed. It's like the truck is doing a chugging movement.. will move your whole body back and forth. In 4th (overdrive) it doesn't do it as bad, but has a slight chug and a very quite backfire/misfire sound. It idles great, when you give it the gas there is no hesitation. Could this be a carb problem? Maybe the timing needs to be adjusted? I'm not sure. Any help would be much appreciated or if you guys could point me in a direction of forums I need to check out. Thanks for your time and I'm happy to be a part of the C10 Family!! |

I would check first for a vacuum leak. If that doesn't fix it, then I'd go to timing and then carburetion.

First off, welcome to the forum Scrubthug, that's a good looking 69! Truckster is correct in making sure there are no vacuum leaks. A vacuum leak will cause a surging effect at cruise speeds as well as backfiring through the carb, especially when the motor is cold. With the obvious out of the way we need a lot more information like what carb, what the cam specs are, what heads and what rear gear? Pics of the motor with the breather removed would be helpful along with a brief history of the motor. ~Ghostrider~
