New Game! Gimme the shaft!

[zachmac]

It's too darn hot in the garage right now to keep working on the car and I know how you all like pictures so let's play a game. Name that shaft. Extra points if you name another shaft and extra extra points if you post a picture of it. Also, bonus points for describing what's different about the fourth one down.

Exhaust cam
Intake cam
Crankshaft
Auxiliary shaft
Driveshaft

Am i doing this right or did i miss the point, lol.

[zachmac]

You got them all but for the bonus points what is missing from the aux shaft?


Extra clue, perspective.

It's missing the offset lobe for operating the manual fuel pump.

Yup, freshly cut off by my machinist brother-in-law with the newly exposed oil gallery hole tapped and plugged to keep oil flowing to the back bearing. No more worrying about aux shaft alignment let alone the possibility of a nasty collision between that lobe and #2 cap bolt should the timing belt ever let go.

Since we are talking about shafts, here is a comparison of the lobes of three camshafts. From L to R:
Guy Croft 3A, 42-82 from IAP, and stock.
Notice how much 'fatter' the lobe is on the GC cam - this keeps the valve open more around peak lift.

That is very helpful, thanks for sharing!

That GC cam is indeed a beauty, now if I could just win the GC cam lotto!
