Has anyone with the baby blower switched headers to zoomies ? Any differences ? I’m currently looking for some laid back dragster zoomies so I thought I would ask if anyone had experience changing them. Thanks

That does surprise me. I do not like Zoomies especially with a front engine car but I have several sets may try them some day.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

Wow I was thinking maybe no gain at all. I wanted something to not stir the dirt up like my downsweeps do at dirt and grass pits. Looks like Chris is going to fix me up. Much appreciated and I will try and do a back to back comparison if I don’t run out of tow fuel money. Funny but not funny. I appreciate the reply’s and Thanks for everyone’s time.

carbs or injection. Carbs don't seem to pickup. My thought is because how carb works and dependence on air velocity thru it in relation to exhaust. Either back pressure or collectors scavenging effect.
