Just a thought, but if you already have the tunnel ram seems like the dual Snipers would be the cool way to go. Seems like the EFI should keep it drivable? I know of people that have run dual 4bbl's on a tunnel ram and driven it daily, but that doesn't mean it works for everyone. But with the EFI seems like it could be made to work?
The TR is just cool. If it was me, I would try and make it work and keep it.
