Reversion
 

Can some one please explain reversion to me. What exactly is it? what causes it and how do I fix it if i got it?
Now let me explain my question. I just installed a 1994 5.0 liter from a mustang into my Glastron that originally had a 302 in it. The new 5.0 has a roller cam and a few people have asked if i have a reversion problem. I have a vague understanding that it has something to do with water being sucked in thrum the exhaust valves. I thought my exhaust manifolds had a water jacket and sealed off from the exhaust.
I'm sure someone can set me straight.
Thanks

This Is Caused From The Intake & Exhaust Cam lobe Overlap. At An Idle If You Put Your Hand Over The Exhaust You Will Feel A Slight Pull Back. On Extended Idling The Water Can Pull All The Way Up Your Exhaust Pipes And On To Your Exhaust Valves. Causing Your Valves Possibly To Warp And Not Seal. After Approx 1500+ Rpm This Goes Away. Alot Of Pipes Are Designed High As Possible And Angle Down To Transom To Slow The Water Down By Having The Water Climb A Steeper Angle Before Falling Onto Valves. Some People Use Turbulators Which Is A Metal Ring Positioned In The Right Spot To Make The Water Turn To Steam And Exit The Pipe.
