Yeah but I feel like it would be a way better platform to build of of than a 2v. Plus I want a screw and that's the color I want. And the hassle and expense of building the engine is already done. Plus he said the trans is slipping a little expecially when cold so maybe with a built trans it will feel a little more peppy. I'm not looking for a 600 hp Truck since it will be my daily, but I want a screw and I can't afford a 12th gen so this looks like the best option.

To be honest navigator heads leave a lot to be desired. The huge intake ports and long intake runners will make great torque and decent power. But 2v can make the same with similar costs. A new trans won't fix the pep. The problem is the torque converter. Navigators have a factory 1600-1800 stall speed. The F150 converter with a 5.4 and a 4r70 is a 1100-1200. If I keep the scab and buy a Screw for a daily I would but it depends where things are going. I will never give up my scab. I have plans but involve a diesel.

I've had mine for 2.5 years and I swear by it. It's been on gnarly jeep trails and just about everywhere else you can imagine. It's makes a WORLD of difference in the bump steer. Only cost 60 bucks. I can't tell you enough how much it improves the driving experience on these trucks.
