Many comments seem angry that anyone not-vetted by them enter their playground. I'm happy to see it and didn't see them insulting your/my toy. They even increased factory power by 200 HP and are interested in suggestions to do better. I think MPFI would be ideal with boost, but a high threshold which only a few have done (Pishta and now Gil Welding). I have a 1964 slant and drove a 1969 slant for decades, but little time to try much custom stuff.
I don't even know why drag-racers continue fussing over manufacturers and engines, since hard for a gas vehicle to beat an EV in a 1/8-mile race and even 1/4-mile (higher level of competition and risk), unless fabb'ed into a custom toy just for track. Ultimately it is about traction between tire and road at the start, and electric drive controls that much better, with instant response.
