VQ35 cam spacer dimensions

VQ35 cam spacer dimensions
Dimensions are in./mm
Note that the 43 mm outer diameter can be made a little larger, but not too much because of dishing of the timing gear. The 10 mm inner radius is the dimension of the cam, so that dimension should not be made any smaller.
Also, the slot leading up to the dowel hole is present in the timing gears, but really all you need is a 6 mm dia hole at a radial position of 17 mm from center.
Special thanks to Bags for providing me with VQ30 cams so I could figure out the spacer thickness.

If you plan to use stock 3.5 cams whether it be in a 3.0 or 3.5 swap, you would be better off getting Tilley's new spacers, but I think these would work better for aftermarket cams which have a different base timing. That way u can drill the cam holes accordingly.

Has anyone ordered them from him or am I the first? This is going to be the start of the 5th week since I placed my order and I haven't heard from him on two weeks. Just want to know if this is standard wait time. I know the first two weeks is just receiving the spacers from JWT but I spoke to him after he received the spacers. Hope he gets them out to me soon.

If anyone needs a set of spacers, I can make them. I have made several sets already, the set that went into Dubbya's engine, and a set that went into Meximax's engine, as well as others. I haven't advertised before because they look a little rough, but they are the correct thickness and they work just fine.
$75 a set.

??? That intake cam spacer looks reversed. The long side should be sticking outward in order to index the secondary and primary timing gears. The short bolt fits into the dowel hole in the cam.

What angle is everyone running their exhaust cams? It seems to be a consensus that 180+2 cam angle is good for the intake side of S1 knockoffs, do people just use the same spacers for the exhaust side?

Hi guys, from pic posted above it is not clear in which way should bolt be moved, and I think this makes difference.
Can you tell me which one is right: 1 or 2? (short -green- bolt goes into cam, longer - red - into timing gear)
spacer are going into vq30de, Maxima QX 1999, to hold vq35 cams:
VQ35DE (2)
Model Years: 2002-2005 (Maxima, and a slew of others)
CVTC: Intake
Intake__Lift: 9.5mm
Exhaust_Lift: 9.5mm
Intake__Duration: 238ş
Exhaust_Duration: 240ş
Intake_Opens: 6ş ATDC
Intake_Closes: 64ş ABDC
Exhaust_Opens: 52ş BBDC
Exhaust_Closes: 8ş ATDC

With the VQ35 cam positioned so that the small hole is aligned with the VQ30 main (i.e. large) timing gear slot, the intake valves open at 6 deg ATDC. The exhaust valves close at 8 deg ATDC, giving a valve overlap of 2 degrees. If you want the same amount of valve overlap as the VQ30DE cams (6 degrees), then you need to advance the intake timing by 4 crank degrees. This corresponds to rotating the cam 2 degrees in a clockwise direction. Configuration 1 gives the correct orientation of the small dowel and the large dowel. Configuration 2 retards intake cam timing by 4 crank degrees.
