Joe, I agree with all of the above but this is my thoughts on street Injection. I have the same Hilborn setup on my Y Block Dragster . I have driven it to a few local cruise within 5 miles . Not easy but FUN ! However I had Two Hilborn injected 427 FE powered cars in the pasted that I street drove and enjoyed! It can be done when driven locally ( 50 miles or less) . First I wouldn’t try it with a automatic. With a stick you can clean it out easier when it loads up. I installed a low speed idle bypass, this keeps excess gas from pouring in to Cylinders at low throttle. I installed an electric fuel pump to prime the mechanical pump on the injection. One of the biggest problems is it will suck the fuel tank dry fast, remember your your shooting fuel in 8 cylinders at once. I guess I’m just an crazy old street racer but it can be done if your willing to put up with some inconvenience and it not your long distance or everyday driver.
