The l67 runs decent, as in i would not be afraid to drive it to work. It does not run good, but it runs. I also know this car had the living **** rodded out of it and it was ran OUT of oil at least once by the previous owner. I want a motor with plenty of power that i can trust driving across the country, not the county. As far as im concerned it will get a fresh breath of life even if its just the plain jane standard rebuild. But since im already going to spend the time i want it to be bigger, better, and faster.
