Automatic? What Head you use? Irmscher Single Intake??My 2.4 stroker is set up with a SSD 45DCOE through an Irmscher intake. It idles well, pulls hard and is fine in traffic and at WOT. There is obviously something amiss with Gordo's specific set-up or a mechanical issue, but the basic SSD concept is perfectly workable. As the saying goes, don't throw the baby out with the bathwater.
