Did he build his rockers for himself only, or did he accually market them? Just curious, also I have a small block mopar engine building manual and it shows an X block that heavily modified with huge bores like 4.10 and the lifter galley has been super modified, how was this done and still retained strength in the block?

I thought that the factory manual showed all those modifications ?
as far as strength goes how old is the article and just how much technology has advanced since then possibly making it all obsolete ?

HEMIFRED, Im not thinking of doing that by no means, i just thought it was pretty cool the amount of work involved.

This was an old book.
