not on a 360 they don't. Ever see how small those 273 manifolds are on a 360 port. They are ok for a 318 but that's about it.

dougs are smaller tubes then tti I believe but you can also use a standard starter I believe.
Spitfires are a nice piece. If you order those make sure you use the COD option.
