A couple years ago my son and I were going to build up a racer from a 1968 Dodge Dart. We pulled the 225 Slant Six and took it to a racing engine rebuilder. They bored it out to 228, put in hardened valves and seats, put in a forged crank and a high performance cam (don't remember all the specs), resurfaced the block, where both the heads and the manifolds mount, and resurfaced the heads, so everything is straight. However, the car was never built up, due to lack of money and time. Engine is still wrapped in plastic and was never installed. We've decided to part the car out. I also have a custom-made header for this engine. Will sell the engine with the heads and the custom header, but all other parts will be sold separately.
