Could have also been the overlooked problem of having too large of primary TUBES(for the post further up) and too large/short collectors? We all know that bigger isn't always better and I don't see why that would not stand with collectors. Also with such long overlap, it wouldn't take much back pressure to cause some awfully bad reversion IMO. Just a thought.....Originally posted by techinspector1
O.K., let's take the case of the Super classes motors that ran better with a muffler on them. Could it be possible that the little bit of back pressure prevented some of the intake charge from being sucked out the exhaust valve at overlap, allowing the motor to make a little bit more power?Last edited by camaro_fever68; 03-07-2006 at 12:07 AM.

It would be nice if this up and down crap would cease.
