Installing a Holley 750 on our C10 SBC
The Next phase of our ’69 C10 Project Begins
Many years ago, a certain enthusiastic magazine editor was making good progress on his C10 project, but then that same editor decided it would be cool to have two C10 projects going simultaneously, and the rest is history. Well, more like history still waiting to be made. To be fair, there has been a ton of progress made on this '69 C10 since we first got our hands on it. After all, this truck started out as a six-banger, three on the tree longbed pickup with a nice coat of house paint red on it, and it was being used to haul rocks every day—as evidenced by the completely sunken bed floor. So even though it is now 'bagged on 20s with big brakes and has a killer 383/700R4 combo, the truck has sat around long enough that just about everything needs to be gone through again. The first step was to uncover the thing, charge up the battery, air it up off the ground, and see if it would run. No such luck.
We got it to turn over easy enough, but there was no way it was going to fire. After some trial and error, we held the primaries open on the 750 cfm Holley carb and sprayed some starting fluid. The truck fired right up for a second, then died. We did it again and held the rpms up over 2000, and it ran like a top, but if we tried to let it idle even for a second, it died. We finally determined that something was clogging up the primary half of the carb and proceeded to rebuild the front half while on the truck, but it was a wasted effort. We decided to save that story for another day and order up a shiny new 3310SA carburetor from Holley. It was exactly like the one we were replacing, except it was the shiny version instead of the classic, and its primaries weren't full of debris.
Once we had the carb in hand, which only took a few days, we went about the task of making the swap, and removing all the rat poop from the area while we were at it. This is just the beginning of getting this C10 back on the road, as we have suspension, interior and sheetmetal upgrades on the docket as well. The plan is to be able to drive it to a few of the summer shows this year, so wish us luck. Check out the install below, and give Holley a call if your current carb is giving you trouble.
