I kinda agree with The Man 1990. A screaming 6 would be pretty cool. As I once again remember the old dirt track days, everyone was running small block Shove or leave it. My uncle built a falcon 6 that would turn 8 grand. Cam, head work, home built tri-power,and headers of course. Kept it as light as rules would allow? Tore up the v-8s and several races set fast time of the night. A 6 would have many scratching their head, smiling, and asking why?!!
