How do you choke it?

[Skunkworks Challenger]

I should know this but I've not really needed to know till now.  I'm considering buying aluminum heads, probably Stealth Heads from 440 Source,  and they come with no heat cross-over I'm told.  How then do you choke an engine with no heat under the carb? I'm restoring a 70 RT and building a 440 engine for it.  PK

That's the cost of playing with performance parts.   You still get some heat rising, though I dont think enough for a choke stat. Well I guess you'll just have to feather the gas a little bit if it gets cold.

Electric choke !  OK, sounds good and thanks for the link.  I'm considering an Edelbrock carb so are they available out of the box with an electric choke?  I agree with 72cudamaan that, yes, there is a cost in playing around.  No body told me to stay away from the Stealth heads so does that mean they are ok? Anyone one with experience with them?

I've always used either the standard coiled thermostat mounted to the intake over the heat cross-over or a manual choke on the Roadrunner.  I had the same question as you about the Barracuda since many of the performance intakes don't have the cross-over even if the heads do.  I'm still uncertain exactly how the electric chokes work, do they use some kind of sending unit and if so mounted where?

Stealth heads.....From what I have heard/read  they are a crap shoot quality wise? Basically your just buying a semi finished pair of castings?  If it were me...I'd stick with Indy! I have a set of Mopar stage 6 heads I'm working on but no were near finished yet.
My only personal experience with 440 source stuff is I bought a water pump and housing from them...I had to finish machining 3 different things on it before it would work on my 440. So I figure if they can't machine something as basic as a simple water pump housing then would I buy something that needs to be machined as  precise such as a set of heads....nope not me! Just my  You will hear both good and bad about 440 source stuff. I figure ya sure some of the negative comments are a flame job....but not all of it! You don't hear anything bad about Indy!...... Can you afford to do it twice?  My Grandfather had a saying with tools " If you can't afford to buy the best...then wait till you can"

                          An electric choke uses a (binary ?) coil spring steel coil in a housing attached to the side of the carb.

I like the idea of an electric choke although I don't know exactly how they work.  I've had my share of problems with choke stoves and carbon plugged cross-overs.  Which aluminum heads?  Yes, I only want to do it once and the cost of a full build on stock iron heads approach many aluminum head prices.

An electric choke works similar to the cross over type.  The difference is the heat is supplied by an electric heating element internal to the choke.  It slowly opens.

I never run a choke on my hot rods, but I live in the south.
