I am convinced that the cam you are looking for never existed. I have a grind that was supposed to be the ‘205’ cam that a customer send to us. The spec’s are close but not exactly what the book spec’s are.

#2120

221/227 @ .050”, 276/309 adv (.006”), .438”/.456” lift, 112 lobe sep

According to your specs the lobe sep would be 114 with an intake center line of 112. We can grind the cam with 114 lobe sep to match your spec.

We can make a reground cam for $79 exchange ($25 core) or a new one for $159. We have new hydraulic lifters for $52.64 per set.

Thanks

I"m thinking that whatever was sent was a "205" replacement cam from MOPAR. But looking at the cam duration 276/309, it just doesnt sound right.
This was supposed to be the "205" specs:
276°/284° duration

.444"/.453" lift

Int open: 26° BTDC

Int close: 70° ABDC

Exh open: 78° BBDC

Exh close: 26° ATDC

Overlap: 52°

Per the 68 factory service manual...
