Not Ranked
I used a 427W with a stock block for a while. 4.060 bore x 4.125 stroke. Cast crank, stock Chrysler rods, hypereutectic pistons. It ran good, and I beat the hell out of it. Ran it on the road course for hundreds of laps. I finally spun a rod bearing because of an oiling issue.
Now I have a Dart based 427, 4.125 bore x 4.000 stroke. Why did I upgrade? Because I plan on beating on the engine even harder over the next couple of years. I wanted to make sure it would last. The Dart block has better oiling, and smaller mains for higher rpm's.
But, the point is, I see nothing wrong with a stock block 427. Companies like Coast High and Keith Craft sell hundreds of them every year. It has some limitations. As long as you understand those limitations, you'll be fine.
