Our program for the GM LS7 castings makes the most from GM's hot rod offering. Utilizing low lift flow technology our ports and chamber design maximize flow across the useable lift range. The factory finished combustion chambers are retained keeping compression ratios the same as stock.
Both intake and exhaust ports best the factory port's peak flow while maintaining small runner volumes. The intake ports have 267cc while the exhaust ports hold 99cc. The flow rates achieved below utilize the factory titanium intake valves and after market stainless steel valves.
