340 Cam Question

340 Cam Question - 06/03/13 06:44 AM

I just bought a 69 340. I have some #'s off of the front of the Cam but cant find what it is. Need Help!! This is on the Cam CD 16003 5-4 800-801

Also, when going back together I want to double check something. The Hollow Bolt in the Cam Thrust Plate goes in top passenger hole? Correct?

Yes the hollow bolt goes in the pass side... look at
the bolt hole and it should go right through to the
intake valley... that is to oil the chain.... no
clue on the cam.... look at the rear of it

That looks like a Cam Dynamics cam. I've not been able to find out anything on their grinds. They were bought out by Crane about 30 years ago. You might try contacting Crane and see if they have a clue. I have some old roller cams that were CD that I got from Koffel, old DC grinds for Modified Production.

I agree. Call Crane. I got specs from erson on a 40 year old cam grind. Was 332 duration, .540 lift solid roller. IN a 301 ci sbc.

Do all 340's have the hollow thrust plate bolt?
Not saying my '71 model 340 doesn't have it, I just didn't notice it. Might have to pull the timing cover back off and check.

All the small blocks had the hollow bolt.. doesnt
mean you have to have it but with the chain it does
drip oil on it to lube it better

not all SB came with the oil thru bolt,it was replaced with the metal drip tab that goes on the lower bolt and hooks in the unused lower hole in thrust plate.

Even ones with the hollow bolt had that tab... every
SB engine I opened up over the years had the bolt
even the 273,318, 340... I've never owned a 360 that
I torn down
EDIT
I throw those tabs in the trash... I havent use one in YEARS
