[rubs his hands together]... its cold here in Tampa today.
I would suggest you take a little time and go through all the BDR threads here on this site. Your question on "who to use for the build" has been asked A LOT and I think you will see an overwhelming response and direction.
As far as options, etc that is too personal to ask. I wish mine was EFI but as soon as my carb acts up I will make that switch. Just go through the options and ask yourself: Do I want it or need it? Does it help or hurt resale?
Best of luck-- I do love my BDR and all the attention she gets!
