Engine has zero miles on it since complete rebuild, professionally built about a year ago I have over $3000 invested in it. It's been started on an engine stand a few times and ran around 30 minutes each time. It's been sitting in storage for close to a year, it's dirty from collecting dust but other than that should be a great engine and a steal at this price. Transmission shifts great came out of a half ton truck, does have one of the bolt holes cracked off of it but doesn't affect structural integrity. Call or text with any questions.
