How can I get more horsepower out of my 351W?
The key to making more horsepower in the 351 Windsor, or any engine, is to move more gas/air mixture through the engine. That means improving the flow in the heads. You can use a myriad of performance tricks to achieve higher head-flow. The first one is making sure air isn’t being restricted as it enters the engine.
Can you put GT40 heads on 351W?
