This photo shows the new aluminum cammer and the one that Larry had cast up some 20 years ago. The new one on the left features stringers in the lifter galley for additional strength. One of the improvements that Larry made was to change the 1/2-inch head studs to 9/16-inch studs.

Here is a look at the bottom end of both the old and new aluminum blocks. In order to strengthen the block even more, Larry moved the head stud threads three inches further down in the block closer to the main webs. As you can also see, he has made the main webs much thicker than they were.

Gould has also fabricated this one-piece front housing for the cam gear drive

On the left is the iron 427 cammer that Bach and Gould ran to shake down the car. In the center is the new aluminum block and right is Larry’s first aluminum castings
