Alot of people run them but I'm having issues with my SD. For some reason if I let my truck run then stop and start it an hour later the plugs are fouled. If I pull the plug right after I ran the engine there fine. No electric fuel pump either, no real reason for fuel to dump after the engine is off.

I think they are a great carb but overhyped. ive used an equivalent holley and a demon and find they perform the same. TUNNED PROPERLY, and the holley is much cheaper.

I just put a Street Demon 750 DP (along iwth a Motorsport X cam)on the 351W in the Cobra. I really like it. It looks sweet, the venturis come polished, the clear site plugs are nice, I like the four-corner idle adjustment. I am using a Performer RPM intake and throttle response is EXCELLENT!! Also, the car starts right up as soon as you turn the key--better than my tpi 305.
