<VV> Heating a 4bbl Centremount 390 Holley

[Western Canada CORSA]

I've seen a really simple, yet effective set up for this.  The car I had seen used a 70's/80's style air cleaner assembly that has a thermostatically operated door in the snorkle that either allows fresh air in, or heated air entering the bottom of the snorkle by the thermostat door.  They welded a fitting for the hot air riser pipe onto the summer/winter cover and ran it up to the snorkle fitting.  Looked simple enough to do, and the guy said it worked like a charm.

Regards,
Joel

I have a 66 Corsa convert with that setup .... Using the 390 cfm Holley!
Note that the carb is really isolated from the engine.....and thus unlike
most carbureted engines...the carb is not heated much from contact with the
intake manifold....that makes the carb act cold.....thus
hesitation.......atomization and vaporization of gasoline is not ideal.
Choke can also be a problem..........so I've converted mine to an electric
choke.....   I've heard that some heat the carb, but I'd like to see how
they do it without cobbling up the installation.
