Tim,
I have gone to the point of doing everything except putting the stuff on
my Spitfire 1500. I have an Impco propane carb and throttle body, and
have figured out a reasonable manifold design, although I think it could
be adapted nicely to a single Weber downdraft manifold that I also have.
I was always thinking of straight propane. The concept of reversibility
depends on what you consider to be a permanent change. Pulling out the
petrol tank and bolting in a propane cylinder is something I would consider
reversible. One note: for safety reasons, there must be a vapor barrier between
tank and passenger compartment, even on a convertible!?! That's something
to think about, but that could probably be approached with plastic sheeting
and polyurethane foam-in-a-can.
Keeping the go-fast goodies was also my motivation.
Tim
