Wait a tick, If the straight 8's were so smooth and I'm not too green(more like a lite olive) when it comes to motors, then why haven't I ever Seen, heard, or heard of a straight 8? did they run like silk to thier graves and why no keep it around if its so robust. Chevy had been using the same engine with newer fuel delivery for 25 years. a lil something called the 350 sb.
