EFI Tests
Right after the blower tests were completed, we moved onto fuel injection. We learned that Edelbrock was making a new EFI manifold based on its outstanding Victor E casting and thought this would be a perfect match for the new F.A.S.T. EFI system we wanted to try out, but we had to know how much power the engine would make with a carb first. So to get those results, we equipped DM with a prototype COMP Cams EFI hydraulic roller camshaft and a Speed Demon 750 carb sitting on top of the new Edelbrock Victor EFI manifold with corks plugging the fuel injector bosses.

T21: same TFS aluminum heads, Edelbrock Victor EFI manifold (PN 29785), COMP Cams Xtreme Energy EFI prototype hydraulic roller camshaft (281/288 advance duration, 230/236 duration at .050, .544/.555 lift with 1.6 rockers, 113 LS) straight up. COMP Cams 1.6:1 Pro Magnum roller rockers, Speed Demon 750 carb, 36 degrees total advance.
