burst plate prob?

I'm blowing burst plates at about 8 or 900 foot mark plugs look good not burnin anything up rev limiter is at 9000rpm can't see my tach and no tell tale if I'm hitten the limiter it will pop the plate right? 496ci 4.310 bore 4.25 stroke 14-71 high helix, bird/110 pump 11:1 comp brodix bb2 heads. I'm runnin a MSD 10 no MAG w/glide think I'm driven through the converter hitten limiter?

 

check your valve springs,

 

The valve springs are good I run a distributor 32 deg timing.No no boost gauge or anything.Can't test again till next week.

 

Checking the obvious that you don't have a leaking intake valve. Some how "fire" is getting to the wrong place at the wrong time.

 

Definatey a valve not seating properly for one reason or the other.

 

Or............ it could be none of the above!

You didn't mention what engine you run, but on some (front panel) 426 manifolds a front discharge blower will pulsate the back of the burst panel (brand new doesn't matter) rapidly and blow it at any given place on the track. A double panel kit will fix it.

If it blows out at exactly the same time everytime, then reread all of the above.

This of course comes from "been there".
The problem with getting old is you've had more time to do stupid stuff!

 

A great idea!!

I took my limiter chip out it was 9000 rpm and no more blown burst plate. Thank god it took me long enough, thank's for all the ideas really appreciate the help. Do you think 10,000 rpm is to much do I have a time bomb on my hands?
