need help with my cam


Recommended Posts

See if there is a letter stamped on to the back of the cam - http://atlanticz.ca/zclub/techtips/cam/index.htm

Find the letter/numbers stamped/engraved on the cylinder head, above the 1 and 2 spark plugs (E88, P79, P90, N42, N47...).

See if you can find the letter/numbers molded in to the bottom of the block, almost behind the driver's side motor mount, right above the oil pan lip (N42 or F54).

Post all of this information and people will tell you what you're working with.

That's not a factory blend of parts. You have an L24/240Z head on an L28/280Z block. You'll have to pop the valve cover off and look for identifying marks on the cam. If I had to guess, I would say that it's the cam that came with the E31 head, which would have an A stamped on the back, according the link I posted. The simplest option, just a different block with the old head and carbs (although I'm no expert on what head or carbs came on a 71 240Z so could be way off).
