Although it's not the best pic, you can sorta makeout how I rerouted and modified "Original" manifold pieces to accommodate the build. Like I said in the other pic the EZ part is fabing and hanging it and the tough part is clean Airflo & Jetting. Datsun has/had some variants of their needle profiles and main jets and with a little mixing and matching you can come up with something that works reasonably well across its entire RPM range and it even passed emissions!p>Uploaded by david.russell.
