Enderle mechanical fuel injection, on the street?
I installed one of the Enderle EFI systems on a blown 426 in a T-bucket (because everyone NEEDS 750 HP[dyno'd] in a street t-bucket with no front brakes). I can't say that I'm all that impressed with the system. I consider myself semi-savvy about things EFI and I was still on the phone with their tech guy several times.
For the effort I'd have gone MegaSquirt. Better system overall.
