Post the favorite small block combo you have had, and why

My brother is on his 4th car trying to beat me. His latest, and coolest is a 78 Dodge Warlock 5.7 Hemi swap with Viper 6 speed manual. I beat him easily the first time. Then he went nitrous and I beat him. Last fall he installed aluminum heads with valves as big as my fist and a custom ground cam. he's somewhere around 620 hp now. That's why I went nitrous. Can't have him winning now after all these years!
