Think were you really want to be at with your Compression Ratio . Gas Price's are said to go way up . That could really cut down on your Driving time . I am building a 327 for my car and now I have changed my build From a 10.5.1 to a 9.25.1 C/R . The 270H Comp Cam is always over Looked . That Camshaft would Work well in a 9.25.1-9.50.1 C/R 327 and be more Street Friendly but still make good Power .
