Anybody know anything about the Cadillac DeVille TBI from the 80s? It is nearly identical to the truck ones but has some extra doo-dads on it that probably impedes airflow but improves atomization. These 4.1L V8s made 130hp@4200 and 200ftlbs@2200. The 305s in the trucks only made 180hp/260ftlbs. I was just wondering if anyone tried running these Cadillac TBIs to try to get some more efficiency out of their motors without hurting performance.
