Chevrolet introduced the Mark IV series big block in 1965, putting them in Corvettes and Chevelles. By 1968 they made their way into light duty trucks like my C10, but only in the 396 and later 402 designations. My truck never came with either and was originally equipped with a 350 small block. The previous owner installed a 454 that the casting numbers indicate came from a 1978 light duty truck. It is a two-bolt main, but has been rebuilt with new bearings and .030 over pistons. The previous owner also installed a larger cam with matching valve springs and push rods. The engine will be backed by a TCI TH350 transmission with a 2,500 stall converter to improve drivability with the larger cam. While it may not be radical, the engine should be more than enough to motivate the truck.  Continue Reading

Something that I’ve always liked about these old trucks is how simple they are. I was too young to work on my dads 67 C10 when he sold it, but I’ve since worked on other GM trucks from the same era. While I’ve done engine swaps and suspension work on them, I’ve never attempted to do a complete tear down until this particular 1970 C10. I spent an afternoon last week digging into it, and it’s a whole lot easier than even I would have imagined. Especially with the help of the factory assembly manual; which is something I like to collect for any vehicle I own. It looks and sounds daunting, but with the right tools at my disposal, it came apart fairly easily. You can take that with a grain of salt, since it was just as effortless as any other 45 year old vehicle with rusty fasteners and bolts that had been rounded off by owners before me.

1970 C10 Project

Growing up my family had a 1967 Chevy C10, a long bed truck sea foam green in color with a tan interior. I think we sold it in the early 90’s, but I still remember how it smelled inside the cab and the burble that the 283 emitted when it pulled up the driveway. Even then the truck was beat; it was rotted in all of the usual C10 places. It was a Tennessee Valley Authority vehicle; it had been driven hard and when TVA retired it, my dad bought it to use for hauling building materials. I’m sure it had its share of patchwork fixes, but it still rose to the occasion when something needed moved. I also remember the day that it was sold, I’m pretty sure my dad sold it for $200 with a bed full of crap and a camper top. The new owner seemed excited at the time; although I’m sure it was turned into a tin can long ago. Continue Reading


In 1976 America celebrated its bicentennial, Gerald Ford was president and a man named Bill bought a brand new Ford F100. Ford Motor Company ramped up production across its 13 factories and sold 1,003,610 other trucks throughout 1976, nearly setting a model-year sales record. Out of those trucks produced, 225,154 were F100’s and 30% of those were built with the same power plant as mine. My truck rolled off the assembly line in Ontario with a 4.9l 300ci 6 cylinder coupled with a three speed manual transmission and manual steering. The only option the truck came with was an FM radio.
