In this video I show you my dads 1976 K5 Blazer that we have been working on. The 350 was getting worn out and burning oil, so we swapped in a newer 305 and so far its been happy. We did notice a power gain, even though its a smaller engine, the old 350 must have been very tiered. My camera quality is not the best this time, But it is what is is for now. LEAVE A COMMENT if you would like to see a walk around video or more videos on the K5.
