I think after 15 years of them not using the motor castings anymore the patent for the cast of the block expires. Then anyone can manufactor the blocks. So there might be aftermarket blocks out there soon that will be built stronger to withhold more power.

Theres a company that just started manufacturing the 67, 68, & 69 cameros again because the patent on the body panel stamps expired. That again leaves them open to anyone who wants to make a little money if the demand is out there.
