68 twin turbo dart project.

I'm kicking around a boosted application but not sure which way I want to go. Two twins, one big single or a centrifugal blower. My car is a 65 so my room is tight unless I hack into the fender wells and reinforce it. The fab work doesn't scare me just want underhood temps to not get crazy. Blower is much easier and linear but turbos are the way of the future to make stupid power. Good luck and nice work man.
