Not Ranked
John,
I would call Sonny Hall @ 979-548-2772. He has raced 428 cobra jets all of his life and now his two sons are racing. They hold several nhra records in the 428 class (not sure of what bracket) and Sonny knows what makes a 428 run. He won't guide you wrong. He built an engine for Jim Weatherall that is a member here.
Fell free to use my name if you call him.
Kelly Mullins
