Slant Six Stock cam specs

looking at the 66 service manual,, lift for the 170 intake.375. 225 was .395 170 exhaust was .365. 225 was .395. You are right as there is no listing for duration or overlap.
the 65 service lists both 170 and 225 intake lift as .375. exhaust as .360. so looks like the specs changed almost year by year. my 63,69 and 72 service manuals are at the shop.curious to see what they list..
