Cranky,
Stupid question!!! Why would you want to turn 9200 in a "big block" 427??? All the TQ & Hp are developed by 6000!!! By the sounds of your question, you've been judging way too many car shows & listening to the waxers talk smack or smelling to much wax...
As a Southern Californian once said "Can't we all get along?"
