Join Mid-Year Mitch as He Unveils the Hidden Stories and Challenges of Resurrecting a Vintage 427/435 Tri-Carb Engine Convertible After 30 Years in a Barn.
After spending 30 years tucked away in a dust blanket, this 1968 Corvette barn find convertible underwent a transformative first wash by YouTuber Mid-Year Mitch. Despite the initial allure of a clean exterior, Mitch uncovers hidden issues during the process.
The Back Story
A year ago, Mitch acquired this silver hardtop convertible from its barn sanctuary. The vehicle, untouched by water for three decades, became the focus of Mitch’s restoration project. His excitement was palpable, and he meticulously documented the cleaning process on his channel. Despite the paint appearing surprisingly nice after a pressure wash, a closer inspection uncovered blisters on the passenger door and scattered blemishes.


Rescued from its barn slumber, the first-year C3 boasted a factory-fitted 427/435 tri-carb engine. However after closer inspection, this turned out to be a replacement engine, a late ’69 427/435 Chevy crate engine block. That Interesting detail just adds juice on to the story. The exterior may appear respectable from a distance, but a detailed look at the mechanical components reveals a less promising reality.
Despite a thorough engine bay cleaning, nests created by critters over the years hint at the challenges ahead. Mitch acknowledges the need for substantial effort, time, and funds for a proper restoration. While the engine’s external condition raises concerns, Mitch remains optimistic about its internal state and the three carburetors.



Delving deeper, Mitch uncovers many issues. Among them, a rusty gas tank, rotted exhaust system, brittle vacuum lines, worn-out bushings, and compromised wiring. Acknowledging that driving it as-is would mean chasing numerous issues, Mitch proposes a body-off restoration to address the multitude of challenges.
