Here are my initial results. A sincere thank you to Blair Patrick, Craig Bloom at Eastco Machine, Ray Paquet, and especially my own dad for helping make this engine project a sucecss. My dad worked and raced for Ford for 42 years and was an FE guy before I was born. We haven't always been close but this project was a true bonding experience that I'm grateful for. I am very happy with the outcome and can't wait to get the engine in the car. I will be using a 4R70W automatic with a 3000 lockup convertor which should be interesting. I suspect there is more power in the engine if I changed the mechanical water pump, mechanical fuel pump, HV oil pump causing TOO HIGH high pressure, the 3.5">3" reducer at the end of my collectors and to some extent, the dual plane 2x4 intake. My goal was a great running and reliable engine for the street/strip. Mission accomplished! -John
