I recently had the opportunity to build a pretty stout 347W engine. This engine replaced a 410W that was in my Ultra4 Legends car. My goal for this build was simple: reliable power, instant throttle response, and sticking (loosely) to a budget.
For Ultra4 offroad racing, fuel injection is a must, so I knew I needed to keep EFI. As diehard Ford guy, I wasn’t about to go LS. Ford Windor engines are beef, have gobs of low end torque, and are pretty reliable into the 500’s on power if built right. That said, what needed to go was the stock computer, distributor, and the engine needed to be able to BREATHE.
