With over a 200K miles of daily driving on it, the little small-block looks pretty good! Our test subject is a ’68 C-code two-barrel 289, though a stock four-barrel intake and Autolite 4100 four-barrel carb was swapped on the actual “day two.” The coil is original and the wires are factory correct, but have been replaced at some point in the distant past. Original exhaust manifolds dump into a factory-style GT dual exhaust system. A compression test showed five cylinders in the 120- to 125-psi range, but three dipped into the 100- to 110-psi range. It’s old!
