There is a Tomei Poncam, this one is indicated on the box and the cam itself as the intake cam... interesting that the dist drive gear is there.....

The client included all of his shim and bucket assemblies, remember those labelled parts?

Each bag contained a valve, a spring, a retainer, a spring seat, and 2 keepers, a lifter/bucket, and a shim.

I took each shim - carefully cleaned, then measured, then and put into my shim kit. The shims coming out were mostly 2.95mm and 3.00mm with a 2.9 and a 3.05 coming out as well. With freshly machined seats, and many "new" valves, I guessed that I should begin with 2.85mm shims to accommodate the seats and valves being cut.

Here are the initial measurements(intakes): measurements in inches.
"L" = loose, but not quite fitting the next size
"T" = tight, but not quite fitting the next size
1 - .011L
2 - .006T
3 - .008L
4 - .012
5 - .013T
6 - .009
7 - .006
8 - .012

So anyone remember Tomei Poncams intake clearance? How many of the valves need adjusting?



More to come......
