This was the first TBI I tried out. It was a Holley Pro-Jection 2 barrel. It’s rated at 650 cfm. It was a very big improvement over a carburetor. Started quicker and just felt much better – especially in the mid range.
Another very noticeable thing was the lack of gasoline smell after the car is parked in the garage. Along with that is the heat soak problem. Sometimes on real hot days it would be hard to start and sitting in a construction hold up or when crossing the border in and out of Canada. Hit it just right and it can be up to an hour of sitting in a sea of cars, trucks and buses idling – a very heated situation. That hasn’t happened with the TBI.
