The Midget stuff no longer uses the traditional 4.400" bore spacing blocks or heads, so that older stuff is no longer capable of competing in that form of racing, and the blocks are made to use the current SBC head that has the larger bore spacing, so virtually overnight, this older cast head and block were obsoleted in that industry. But the good news is as you say, the street market will flourish because of it, and I should be able to accomodate them with there needs and desires for both the 4 and 6 cylinder crowds.
