Opinions of this Slant 6 video

He states in this video many times that it's not a 'how to' vid with specifics. It's more of 'history' of the engine.
He's a member on here, I think his username is whitepunknitro. You could try messaging him directly, and I think there are other slant lovers on here. That said, the guys that can answer your questions are probably going to want a lot more info... what body, what trans, what rear, what gears.. and what do you want out of the car?
As I have stated, I want my car to be driven on the street and I want to be able to cruise at 70 to 75 mph on the highway. My car will be taken to local car cruises and I do not want it to be a push over. I do not intend on drag racing the car, However, I want the car to accelerate and smoke the tires in first and second gear with my pushbutton 904. My car is a 64 Dart GT/225.
