Were these ever run in on the motor? Any dyno chart showing what the power band was like with them?

Those are huge!

[bentvalves]

wai wai wai 312's??

more light needs to be shed

290's!

[sldwys]

These cams were run on my motor several times but not dyno time so dont know... But You could rev to 9 1/2 rpm with supporting headwork.... I brought them "supposebly new" from a japanese garage... They were old and sitting on the shelf for a long time... Basically though they are mint as.

More Top end cams Somthing like these cams with a garrett or hks gt28 turbo would go nicely ( .64)

All Will be revealed about the 312's once they arrive in my hands tomorrow

I have been told by my engine builder that they are 272 / 290 I will get pics if you want them.

If I had $500, this thread would have ended at my first post.

[sldwys]

anyway heres a few pics....

Even better for you guys.... 1 is a 272 10.25 the other is a 312 10.25

noted on intake Cam 272 10.25 noted on ex cam 78 10.25

to work it out for the ex cam -

78x4 = 312deg (Nissan spec = "duration" / 4)10 = 10mm lift25 = centre of valve timing @ 35degs

and heres a few "teaser" pics of my newbies http://serion.web.fc2.com/up_200808/16lars_05.html http://serion.web.fc2.com/up_200808/16lars_07.html http://serion.web.fc2.com/up_200808/16lars_08.html http://serion.web.fc2.com/up_200808/16lars_09.html

ks13 - are there any markings on your JUN cams? As I think my new Cams are jun... they just say 78 10.35

[bentvalves]

I believe they are JUN custom grind.

no markings just read 68 - 10.35

[themadscientist]

just multiply two digit numbers by four to get the three digit duration.

I have serious doubts an 8 port head can flow at those kind of RPMs. CA18 ports are not that substantial. 272s are possibly too big IMO.

[sldwys]

here in NZ we have 8 port heads and 4 port heads, my cylinder head is a 4 port head, ported also - Oh... with a custom intake manifold + q45 AFM, thats what i thought so my new cams are 312

[themadscientist]

solid lifters and a fully balanced crank? Are you ready to throw absolutely all low end out the window, suffer through the ramp up to the stratospheric leading edge of the powerband and cruise at 9000+ RPM? 312s are the kind of cams 10000+RPM full tilt NA motors breathe through. I highly doubt any CA18 can make effective use of cams like that. I look forward to your dyno charts to see what they actually do.
