I knew a guy who had a balanced and blueprinted 340 in an older dodge valliant. He won a trophy every week at the local drag strip. His brother totaled it, and I got his headers, high-rise intake manifold, carb, tires, rims all for a song.
I had already driven it across the country and put a lot of wear and tear on it. Then after adding the parts I blew a rear end, u joints, and tranny in about a year, lol. I loved it and hated it
