Cam specs for 273?

They are in the very back of the 65 Plymouth manual.

In the back of engine chapter 9 for 66 and later.

The cam duration specs are in the camshaft section.

The lift is at the bottom of the valve spec section for each valve, intake & exhaust....

Found them! Thanks for the clarification KK. So the correct specs are 248° duration, 26° overlap ,
.415 intake lift, .425 exhaust lift. tmm
