Been looking at and reading about the new Street demon carbs.. I have been wanting to update the stock AFB on my 67 440...
Would this carb be a bolt on?? I understand the electric choke, but would my stock linkage ( throttle and Kickdown) bolt up and would my air cleaner work?? Appreciate any knowledge on this..

If not I assume a new Edelbrock ( avs) will??

67 Coronet 440/727

Me and my buddy just got two of the Street Demon 625's, you'll probably get the 750, but both of ours bolted on and all linkage bolt right on. I had to use a carb spacer because of my spreadbore intake.


Still looking for LM29H1B415501, '71 Demon 340

I bought a 750 for my 340. The stock throttle stud would not work since it comes in from the back side of the arm on the carb without taking the carb apart. I had to order the street demon mopar stud at $25. You would think that the stud threads would screw right in to the throttle lever but I had to use a nut. The carb works great. The best I ever have had and that includes TQ's, eddy' and holleys. The air filter I have worked, it is the black mopar flat top die cast air cleaner.

Mine is a Speed Demon, but pretty close.

On my stock dual snorkel, the choke linkage near the top (at the butterflies) just barely hung up on the rim of the air cleaner. The smallest amount of bending and tweaking on the air cleaner base and then it cleared just fine. It took barely any bending at all, and it is on the bottom, so it is not visible anyway.

The "Speed Demon" is basically an update of the Holley design. That's what I have and I like it. They have been around for a while.

The "Street Demon" is basically a rework of the Thermoquad design. They are newer and I have no firsthand experience with those. Sorry...
