Holly makes a intake for the tbi with the matching unit. I think they called it the projection.
Intake number 300-66 not sure in the tbi unit is still available. I think it was 600 cfm

Would any think a procharger would be best or no cause the tbi heads suck so much

I wouldn't waste my money on a performance upgrade such as a turbo or supercharger on a truck with TBI heads still installed. TBI heads were made for low end torque, not performance street trucks.

You can have the same thing by removing the ridges around the bores. Everything else is extra.
The 45hp claim is probably on a fully built engine where the TBI is the restriction, therefor this mod allowed the engine to make an additional 45hp because it reduced airflow restriction.
