Wall Street analysts are growing increasingly optimistic on auto parts maker Holley . JPMorgan's Christian Carlino and Bank of America's Alexander Perry upped their ratings to overweight and buy, respectively, from neutral Wednesday. Carlino's $7 price target implies an upside of 59.1% from Tuesday's close, while Perry's $6 forecast would mean shares rise 36.4%. Electronic fuel injection is one of the company's largest businesses, accounting for 15% of sales, Perry said. Despite the bullish turns from two major Wall Street names, not every analyst is as optimistic.
