My own opinion and I will not place them in order of baddest.......
Bob Gliddens Arrow
Ricks ss/bm Valiant
Don't know owner name but the was a Dodge that ran in comp elim. about ten years ago and had a twin turbo small block that ran 6"s
I know it's not a small blcok but Billy Giggs L/A Daytona that ran ran low 9's with a srt4 motor.....Just my 2 cents
