Hot fuel vapor carburetor

[oil pan 4]

Then I need to find something to seal the carb to the plate that will allow for maximum heat transfer.
I'm thinking just RTV, no gasket.
Unless anything can think of something better?

I'm not worried about heating the intake manifold, I think it will get a paper gasket and RTV.

Hmm. Thermal adhesive. Like thermal paste/heatsink compound, except it hardens like glue. If it doesn't need to harden, stick with the paste.

I did not know of such a compound.
I am going to have to stick with paste I thing. I don't want the carb and the plate permanently stuck together.
I'm going to working on some tuning and I may switch between edelbrock 650 and 800cfm carbs once or twice.
I can try sloping some thermal paste on there and see if it holds vaccume.

It comes in different "strengths" too, which dictate how fast it can transfer heat.

I'm waiting on some "GD900" from fleabay; it has one of the higher/highest thermal transfer rates vs price that I could find.

This may be OT, but have you thought about adding an electric pre-heater to the carb manifold as well, so it doesn't have to wait for the coolant to get warm? Could be a little insurance against carb icing too.

I have a thermostatically controlled intake. It gets warmed air as soon as the exhaust manifold starts to get hot, which is around 20 seconds.

[ThermionicScott]

I know, but before that!

I actually have hatz diesel intake heaters I could use.
For cold starting it's actually not a terrible idea.

The carb heater plate is the dirty old looking thing between the intake manifold and carb.

Any improvement in FE?
