Road/Speed Demon; What's the Difference?
Take two. I guess the UBB screwed up my post the first time so here it is again. I want to get a Demon carb for my Jeep, a 401 powered J-20. I want the Demon for its superior performance vs any other carb, but I don't know what the difference is between the Speed Demon 650, and the Road Demon 625 other than 25 CFM. Can anyone enlighten me? Thanks.

The Road Demon has a choke set up ( I beleive electric) on it versus the Speed Demon having no choke at all.The Road Demon is jetted slightly leaner than the Speed series for more economy.Other than that they are fairly similar carbs,for your app I recommend the Road Demon series.
