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.
