38 21 stud rebuild

[melisa]

Rebuilding a 1938 21 stud ford engine.. the engine came with champion #7 spank plugs which need changing. What is a current shark plug I could use in it's place?
It came with two fuel pump push rods each a different length.. Which one does it take the longer or shorter one?

Thanks in advance. Melisa

Champion D16,or NSK A6

Pushrod is to suit height of manifold flange that takes the fuel pump mount. If said flange height is about 2" tall, it takes the longer pushrod.

If it is truly a '38 then it only came with one pushrod (option). The '38 valve chamber cover was aluminum in '38 and thus, the "short" rod is proper.
