not everyone has 1500 to 3000 hp looks like he makes some where around 650 to 700 so what ever he chooses it will work. Not a ford guy but I have seen mustangs run in the high eights with I guess a 8.8 with 4 lug wheels but I also seen cars with 8 3/4 go that fast too. but if he did put a dana in it . I think it could be done for under 1000.00 dollors not 1500.00 just for the center section for the nine inch. and not every one has a million dollors. people saying 15 to 50 pounds difference ?? I don't know what it would be I guess it depends on the length of it . and how much do you think that is going to slow a car up?? a couple hundreds?? I guess that's a lot if you have a super stock car. but most people are bracket racers just change your dail or put a big block in in or more spray to cover the 50 pounds
