SRT’s new Drag Pak cylinder block is cast and machined by TEI. TEI’s low pressure sand process and Grob 5-axis flexible machining center produces a machined block of the highest quality. On August 30th the engine performed tremendously on the big stage at US Nationals for the factory stock class. We were thrilled to get a glimpse at the action via driver Leah Pritchett’s Instagram page. Click on the images below to see her reference to TEI’s role….”from CAD to cast”.
