Thanks a lot ,
I only read about the o.h.o cam and that they used it together with domed pistons on my doae heads, so I thought a cam wich is near to those datas would be ok for me
The Specs:
advertised duration = 326°/334°
duration @ 0.050" tappet lift = N/A
duration @ 0.100" tappet lift = 233°/238°
0.564"/0.587" net lift (0.025" lash)
102° lobe separation angle
126° overlap (that's not a typo)
Intake lobe centerline = 101° ATDC
Intake valve closes @ 84° ABDC
That is an old technology cam. Compared to camshafts available now, that one makes no sense whatsoever.
I don't even understand how it works at all.
Wyandorf machine has the bushing "kits" for $400. You can do them yourself but before you put the engine together. As George says , "it's a deal".

If you have already built a street engine, I wouldn't tear it apart to install the bushings (which you will need to do). A race engine should already have had them.
If it isn't put together yet, by all means install the bushings. As "they" say, it won't hurt?
Not to taint anything but many engine builders have found that if they recommend the bushings, they get the work. Makes sense.
