 Just like the 2-V TBI setup, the 4-V unit tucks neatly under the air cleaner for a clean “retro” look. The convertible hit the Dynojet once again for our “drive loop” and as expected, we did see a slight drop in fuel economy (2 mpg), but when you factor in the fuel economy the Autolite carb was getting, it’s still an improvement over the stock induction setup. As for any power gains, we’ll have to report back on that in a future issue, as the dyno operator got a little giddy on the power run and bent a few pushrods. We suspect the power numbers on this near stock engine would be similar to the 2-V TBI though.
