A major change in nitro drag racing needs to occur. The greatest drag racer in history, "Big Daddy" Don Garlits long ago advised a return to 1/4 (1320 ft.) nitro racing via one magneto and one spark plug per cylinder. This change would achieve what many racing fans want - 1/4 (1320 ft.) without breaking the bank. There would still be 300 mph runs but not unacceptable speeds. Don't understand why NHRA hasn't already followed his guidance. Give the teams a 2 year notice to use up current cylinder head inventory and other parts. Then prepare for the return to 1320ft racing!
