This motor was never in a race car, or in a derby car. It was in a street car driven on pumped gas. I have the build sheet for this motor. This motor is a good strong runner. It was pulled out in September of 2011 and was drove into the garage when it was pulled. It was in a 71 chevy short box that had been in a minor accident after beeing restored/fixed up. I say that because it was not a show room resto, and was made to be driven. It was always going to be fixed but was never gotten to. Body was sold and motor came out. It has around 20,000 miles on the rebuild and needs a good home. Motor is in Kearney Ne. I would like $1200 OBO or I would trade if the deal was right.
