Had the cracks there also. I doubled up the mid tab. (Thicker). Also added 2 additional laterals. no more cracks. Don't laugh at the Shield. just lazy. Reid case with the internal liner.Remember at the hit, the motor want to take a vacation rewards.

Is there a common theme for this? All BBC's cracking? All 1000 plus HP? Are they all 1/2" plates? I have an 08 that has always had BBM in it, 1/2" polished, looks like new (so far). Just curious...

Correct.......plating and coating are for show cars and have no business near any race car of mine. It's a proven fact that chroming embrittles aluminum.........BIG NO-NO.

It is......basically an adapter plate that changes the bolt pattern from Mopar to GM. Kinda like how Stahl header adapter plates work with a countersunk fastener.

So, safe to say a 1/2" midplate and less than 1000 hp should be safe? I clean mine after every race and have a little check list of possible loose / worn items i look for. Did not think this would be one of them until this thread.

Ed, I got up with S&W and they are not sure if any of the patterns they have are for the 06, so I would need to send the old plate to them. So not sure what we going to do yet, I know he has someone that can CNC one for him in town(Iowa) so we will see. but thanks for the help.

Buy some 6061-T6 material and with a jig saw, a grinder with some sanding disc and drill press you can make your own in less than 2 hours using your old one as a template
