Welcome to CHR. I saw your resto video; nice work!

Richard knows what he's talking about. I've always been leary of Nitrous but I think it has come a long way now. However in your case I would worry about how many 2L inlines have been puffed and what the proper fuel/gas recipe should be. I would definitely try to research it first and talk to NOS people etc about it up front.
