Wow looks like your friends going to have one killer dakota when he is done. My other friend had a 6.1 stroked to a 426 like my friend with the 71 duster. He too ran 9.60 at 140 in the 1/4. The 426 was in his 87 dodge dakota. He sold the dakota and put the 426 in a backed half 73 duster and put it on alcohol. I think he is runing 9 flat or a high 8 second 1/4 mile pass now.
