I bought
@rumblefish360 's D64. I also have the Offy 5488 that is in the video. I will be slapping them both on the 360 I'm building and will post up the results in the future. You can see what I've done on them if you look back on the what I did to my car today thread. Within the last two months.
The Eddy is a 180* manifold.
The Offy is a 360* manifold.
I may even compare compressive vs straight linkage too. I really don't care about mileage.
