    So tonight I removed the an item of concern. There was a screw inside my airbox (under the filter) holding it down onto it's proper position.  
 
Hi Todd,
 
I'm fairly paranoid about items that can get ingested too.  All hardware inside the airbox must be drilled and safety wired.  
 
    But more disconcerting is another mod. Many builders have done this and that is the plastic steel (JB weld or Devcon) inside the secondary intakes in the end plates.  
 
I certainly share your concern about that mod, and it's the single reason that's kept me from using the 6-port housings that I have in the garage.  It's also a concern for those who are making their own PP engines, since you have to fill that port up with the epoxy stuff.  While it doesn't seem likely that it would crumble off, and get into the engine, it would always bother me.  
 
BTW, I know Tracy's test stand engine has eaten it's share of JB weld (consider the owner <g>) without any damage, but maybe he just got lucky.  It's also possible that Murphy's law has an exemption for engines on the ground :-)
 
Cheers,
Rusty (perhaps the only one with a copy of Bruce's video on DVD)
