JSimpson, you are right on target. The effort that went into this conversion is mind blowing. Not only did he have to deal with the basic C4 puter issues, but he had to retro fit the electronics into the C3. With that being done, he then explored the lack of space and still came up with a way to shove all this stuff in the hole. The only thing I don't like, is you can see his Cone air filter squeezed between the radiator and the water pump.
This is the same issue I have with most TPI conversions. That is stuffing the air cleaner (and usually a small one at that) right behind the radiator where it is sucking hot hot hot air. TPI engines love cold air and will go hyperspaz the more cold air you can feed them.
Other than that, I :BOW to this guy. Had I seen this pic early on in my project, there is a very good chance you would be looking at this same basic kind of thing sitting between the front tires of my 69. When I was doing research, I was pretty much told by all the major super charger companies that there is nothing known of to fit the C3. All the measurements I pulled from on-line sources indicated the width and height just a tad too much to clear.
