To also let everyone not wanting to do a DOHC setup I can also make a version where we can convert to a HTD timing belt system and do away with the chain.

5 axis NC mill. Bet that black reel to reel tape was fun to program on a punch machine.

I can make the plate accommodate both heads really.

Just a matter of having an idler mount point left vacant.

I have that Z5 head sitting on my shelf.

Single timing belt drive pulley to drive the intake cam, and a chain to drive the exhaust cam.

I am currently working on some GTO vents, and plan to machine a proto timing plate afterward. Ill post a machined image soon. couple days type soon.

Looking over the pump system on the Datsun. The pulley of the factory diameter wont slip over the whole pump housing. So that is out of the question. Without ordering a pile of pumps to samples I don't know how I could design around other models.

The Idea of moving the pump outward and continuing to use the factory V belt or custom serpentine is the best solution. The less we have to buy is best.

I could machine a custom pulley that resides within the timing belt belt plane for the water pump, and I could just place the factory pump right in its factory position.

I am picking up what you're are putting down D.

Rather than put the pump on the accessory belt plane we incorporate it into the timing belt system.

By doing that we would only need the one idler. Not two. The water pump would act as the removed idler. The tension sprung idler would remain on the opposite side of the system.

Just we would have to find a pump that resides at the exact stand off distance
