start talking to some big block guys. ask them what kinda flow your gonna need.....thats what i did.........my buddy was a big block mopar fan.......and when i was doing this and learning........he helped me out on that.......but my 393 already exceeds that 450 foot pounds of torque rating.......now imagine another almost 34 cubic inches.......thats alot
what i did was also look at what a good big block around the same cubic inches were running.......as far a headers.....and look at what a 427 big block would use when determining what the horsepower and power band you want........if your very aggressive, you probably would need a 2 inch header. especially if your spraying.........now what kind head is going to have exhaust ports that size... hmmmmmmmmm.....really makes you think when you start relating it to something similar...
