These little 3" stroked engines need better valve springs than the -929 cam springs used in a stock Z-28 302 engine!
Of course they will blow up at 8,000 rpm using the stock springs. Float the valves and bang!

Springs would only be the first parts to replace. The crank, block and heads were the only pieces in a '68 Z28 reliable at 8,000 RPM.
You reved them up high enough to straighten the generator fins
