Duane, its available now. A speed pro set up would work on your big block. They would drill the intake above the ports for injectors and put a throttle body on it. Mr fix it, no fuel lag? Is there a vaccuum in the intake(no air) until the throttle blades are open? The air is allready in the intake before the throttle is open. The injectors at the port allows the fuel to be there too. Go drive any port fuel injected motor and see how much crispier the response is at low rpm versus a carb. That lag and poor distribution in a carb are the main reasons fuel injection is better from a performance stand point. Idle quality, emissions, fuel economy and elevation changes are added benefits.
