Hi All,
I need a little advice here. I installed the new engine in my '72 B
roadster, everything went
very well, engine purrs, except for one little detail. The engine had all
the emissions stuff removed when I got it, and had a 25D dizzy. It also
had it's original HIF carbs., and had the vacumn advance plumbed to the
manifold vacumn. Now everyone knows that is backward from
what you need( yes I did check and the dizzy is a vacumn advance model).
The only thing is I don't see any ported vacumn connections on the HIF's, so
am I stuck here? The way I see it I have basically three options. 1. go to
carbs with ported vacumn for the advance. 2. go to a mechanical advance
dizzy without vacumn advance. or 3. get a dizzy with a vacumn retard. What
is the opinion of the folk on the list as to the best option? ( For the
time being I'm thinking of pulling the HS4's off of my '70GT and running
those for a while, that engine is coming out for a rebuild in a week or two
anyway....)
TIA
Harlan.
