Box Performance

Called here looking to get my SBC rebuilt and ended up talked into an engine they had in stock. Feel like they just slapped it in with left over parts. Runs awful even after taking it back. Spent last 8 months trying to get it to run decently. They tell me it runs good and I should be happy with it. Leaks all over, bolts with 1 or 2 threads holding them on, new engine on broken mounts. Take it back and they act like they do not believe me. Having another shop build me a motor the way I asked these guys to. Plan to swap and be done with Box.
