Id like to find out if anyone on Mopats is running a STR 12 crossram on their 340 to find out how it works. Ive been told by many people that they never worked right due to a bad design flaw . Unburned gas sits in the intake and has a tendancy to blow up and damage the lid cracking it on start up . Is this true ?. its a cool looking manifold and seldom seen on 340s. Any info on this intake would be helpfull id like the good and the bad on this cool peice how it works if it can be modified to be reliable etc, thanks Moparts for the post its a great site.
