That deal with Kyle was a scary, scary, evening. There was a heck of a fire going.....and a garage full of race cars and collector MoPars. It could have been real bad. We had an extinguisher, and there were some guys around. But, if something like that had happened inside an enclosed trailer....it makes my blood run cold.
I think on that deal part of the problem is that the MSD box had gone bad, and caused it to cough up through. Whatever the cause, it was a bad deal. He has the intake working well, now, though, and the car idles and drives as well as your new 300. But, he does have the Wilson sneeze valves on it, now.
Bob could probably answer this better than I, but I think the Indy intake and the old Rat Roaster had the most problems with this. I've heard of it happening with the regular cross ram, but not very often. I think the fact that the new MP crossram has core plugs on each end would be helpful. I think the older ones, especially the Diamond Elkins deals could do it if you weren't careful.
I use the new MP crossram with no issues, but I don't street drive it. It doesn't idle around much, or spend a lot of time where it could load up and cause an incident.
Bob, I'd love to see you put a cross ram on that 65, a set of headlights, and get out there with us. I understand why you are hesitant, but you belong out there with us Geezers. That car has NSS written all over it.

This post is directed to Bob George... Is this potential problem isolated more to the Rat Roaster style of Cross Ram Intake ? The reason for this question is that I just installed a new M/P Cross Ram Intake ( M/P part number p5007534 ) with the two top access panels on my 472 Crate Engine. It will be a street car only. This talk of intake explosions has me concerned enough to look into the Wilson Manifold Pressure Relief Valves. Would it be necessary for this later style of intake ? If I do install two ( 2 ) of these pressure relief valves, where would be the best location on the intake to mount these valves ? Thank you in advance for your response...
It is not necessarry on the factory X-rams,hemi or wedge that have the expansion/core plugs and the manifolds are more rigid. Large open plenum box style manifolds like Indy and Rat roasters with areas that can puddle fuel are more prone to blow apart.Indy uses the small bolts for just such reason and large open manifolds with no center connecting rib top to bottom with out any attachment bolts are also prone to pop.Letting the top lift causes the attaching bolts and thread bores to break,but the fire after the explosion is what worrys me.Also letting the top "lift" can do a lot of other damage especially if it pulls a fuel line off and the pump feeds the fire.In Kyle's incident the hood was open and the manifold top as well as carbs launched and ended up on the rad support.Only quick thinking and appropate action prevented it from being a disaster.And Russ's in trailer pop could have been the same.That anyones comments that it will or never happen to them doesn' need insurance since they will never have an accident.But to answer the question about the stock factory style including the new MP X-ram,no you don't need the "Snezzer"valve.
