Installed the original camshaft back in the engine and degreed it. Since I didn't have a solid lifter to use for degreeing purposes, I wound up disassembling one of the original hydraulic lifters and replacing the inner spring with a 5/16 nut and and reassembling it. It worked great.

I reused the existing timing chain and gears since they had all of 400 miles on them (and 20 years since the dealer installed them).

The factory intake centerline spec is 110 degrees and it turned out to be between 108.75 and 109 degrees. (after three readings). So I guess it is a little over one degree advanced which is perfectly fine with me.

Here's the factory specs on the 460/365 horsepower camshaft:

engine...............lobe lift.....valve lift.........open (btdc)... IN dur...EX dur....overlap.......hp.....................torque .........comp ratio
1971-460(4v).....253/.278...442/.486.......16 deg..........256.......270........36 deg .....(365hp@4600)[email protected]

256°/270° @ SAE
193°/206° @ .050"

.253"/.278" lobe lift (.443/.487 valve lift)

110°/116° lobe centerlines –
