Enderle mechanical fuel injection, on the street?
Generally, manual injection does two things well. Idle and flop wide open. Any part throttle operation kinda sucks.
There's a seller on Ebay......very reputable. his screen name is alkydigger. Might have a hyphen or something, I cannot remember. He sells manual to EFI conversions. Might get in touch with him.
Here he is. He has his own web site.
