carb ?
 

Will holley jets work in a demon carb its the might demon all i see in the summit magazoine is holley jets so i was just wondering if they work if there all the same

Yes, they are the same jets. Many parts are interchangable, since the demons are based on Holley carbs. I am planning on buying a Demon for my 1985 GT, so I have been gathering info on them.

Are the Speed Demons a double pumper style and available w/manual choke?

Available as a double pumper or as a vac. secondary carb, do not think they come with a choke at all.

road demons are vac. secondary... and an electric choke is an option..

I'm looking to get the SPEED Demon/mech. secondaries. Are they available with a choke? Also, who has the best prices on Demon Carbs, ebay had them for $439 + $15 shipping that came with a dual line kit.

That is Summit's price too. It doesn't come with a choke. An electric choke kit is available seperately for $51.95.

I live in Canada and I don't use a choke. I just nurse the throttle for the first couple of minutes, but then again, the coldest weather I drive it in is the mid 30's.
