Cam ID question.

[RAT ROD AL]

I pulled this cam from a 64 273 2 barrel motor. Looks in good shape. Can anyone I D or get any specs or info from these #s

TIA.

One of the better 2 barrel cams.

2 barrel through 1967

For comparison on the grinds
Scroll down to the 318 roller cam, your cam has more lift than that one.

I am running the stock '89 318 roller cam with a 1406 4 barrel and it is handling it just fine > low end, top end, never misses a beat.

Take a micrometer and measure the cam lift on the high side, multiple that number x 1.5 and see if the lift specs match the chart above for your cam.

You have to subtract cam base circle diameter from the over the cam nose dimension before you multiply it by 1.5 rocker ratio to get valve lift.

Also keep in mind mostly rocker arms rarely are the ratio that they are supposed to have and are often less.

I don't see any cam #'s on that sheet? It's more than likely been swapped out at least once in 60 years.
