I just received a camshaft sold to me as "for 1.6 believed to be fast road but not sure"
Just wondering if anyone could identify it for me, I've searched google with the numbers stamped on the camshaft and not got anything too interesting. To me it looks like it's been reground, as the material between the 'flat' end of the cams is ground back roughly, but quite obviously after the camshaft was cast, and it also seems to be a lot shallower between the cams than i remember my standard one to be.
The markings I can find on the cam are:
"HF" stamped into what i believe is the dizzy end of the shaft, smaller end with the short dowel type bit on it instead of the hole? not at home atm to check which end that is and i can't remember off hand. Personally I was hoping that this stands for "Have Fun".
"10326" on the opposite end of the cam shaft, again stamped. I'm guessing this is the production number, possibly of the blank, or the original GM camshaft if it's a regrind?
"R9" This I thought at first was scratched into the end but looking closer it's actually a series of tiny dots stamped lightly into the materal.
"79" and "26" on the actual shaft of the camshaft, between cylinders 1/2 and 3/4.
It also seems to have an offcentre circle 'cam' on what i believe to be the dizzy end, in between the dizzy drive part and where the first bearing would be (what would you call that anyway, guide?) I can only imagine this would be for balancing? But i'm not 100% on that as the camshaft is obviously reasonably well balanced by design, as it opens cylinders 4 times per revolution, and so by design the lobes are seperated by 90 degrees, or it fires randomly.
Rep offered for help in identifying, because you deserve it just for reading that lot lol
Cheers :thumb:
