Once upon a time my 72 v-8 mav had a 2bbl carb with a heat pipe off the exhaust manifold to heat the choke.No elec connection on it.Look for a rusty pipe end sticking out of the exhaust manifold.Its small,about 3/16" It will be on top of the manifold,close to the flange end of it.I have seen the 72 with electric chokes so it could go either way.Good luck.Hope this helps.
well there is an electrical wire and thats what got me thinking about this...........so asked all the people here. but is an electrical choke better for performance or not. also i was looking for an intake and i want to get an air gap but i need a four barrel carb right? any suggestions for a 4bbl carb?
