K CODE CRANK MACHINING

While certainly no expert on the matter, I've always understood a 30/30 crank should be as viable as a 0/0 crank for spirited driving in any engine application save perhaps an all out race car.

When the original engine in my 66 GT350 blew during a road race in 1973 the crank was spared, only the block was toast.
The owner at the time had it turned 30/20, rebulit the engine using a Boss 302 D1ZE service block, and continued to race for 5 more years routinely shifting at 7000 RPM.
