My 340 is running hot I think.. I need a sanity check.

Actually, if it started better with the throttle held open some then DON'T pump the pedal before a hot start..... it'll just make it worse. I'd agree on a carb heat shield. Holley makes a composite one that sells for about $30 that is about 1/4" thick.

And OK OP on the ground condensation. Pretty normal, and the clean tailpipe sounds great; does not sound like anything is very rich at all. These cammed, carbed engines often will just not start like a modern fuel injected car so I would not consider the 'questionable'. My son's 340 starts better hot by holding the throttle open a bit. It uses a Holley 670 Street Avenger (4160 type).

BTW, OP what ignition system does your car have?

I was just reading a thread on the carb spacer and potential of fuel boiling... It was a pain in the *** setting up my Holley to work with my factory Linkage so the idea of adding thick spacer is not appealing although a 1/4 " deal seems doable.

My ignition is an MSD billet pro Dist., MSD 6A controller, blaster 2 coil and 8.5 mm Taylor wires with champion plugs. I gutted the Ballast resister and jumped it out by soldering in a piece of 10 gauge wire.
