As part of my build, I am considering using the factory dual quad for street-ability. I'm assuming it'll have better low end than the Wieand dual quad. My thinking is I would port each runner on the factory intake to flow a bit more than the intakes on the heads - for top end. But, I had it in my mind the cast dual quad was a dual plane but looking at it this afternoon it's more of a split plenum. Simply a wall in the plenum separating the driver's and passenger side runners. I've got a Wieand dual quad as 'backup' but wanted to get some opinions/first hand experience. Does the cast intake have decent low end? If so, is it a lot better than the Wieand or are the pretty similar. This is no trailer queen and drive her on weekends for errands and take her on road trips all over Texas ... and beyond :) Will be running a 3.73 rear end, expect about 2600-2800 rpm stall on the converter. Haven't finalized cam specs yet. Anyone have any experience running either intake or both? Thanks, Duane PS I know the cast dual quads crack at the heat riser passage. Mine's cracked and will be repaired if I use it.

I posted this topic on another forum and there was one strong opinion that there would be no difference in low end performance between the factory cast dual quad and the Wieand aluminum dual quad. I thought I would respond to close out the thread. Duane
