Looking for old crane cam card.

crane doesn't make this cam anymore so it isn't on their website

HIT-284-2-nc

I've found other specs online but I'm looking for the install height for the valve springs.

Thanks

Call Crane. I had questions about my Comp Cam and they had all the answers. Great customer service IMO

Ask and you shall receive. Can't believe I found this for you (usually old part numbers are like deciphering the Rosetta Stone), but here it is.....

I dont understand.
What valve springs are you using?
The cam does not dictate installed spring height.

Re: Looking for old crane cam card.

Yes the cam don't really care what the spring's installed height is or has anything to do with installed height.

Your installed height is set by spring pressure, valve length, locks, retainers, shims, coil bind height of your springs, etc.

The common sbc spec is 1.700" but that all depends on your setup, and springs.. Taller installed height will lessen the spring pressure, where shorter installed height will add more spring pressure.
