I has a engine update on a Cuda 70 with street Hemi for AA/SA in Sweden.
2 things I need to clear up, as I hear dual messages on.
I has bought the new Mopar Performance block and will change the oil pan.
The oil pan in the list was OEM 6Q ( as I used before )
A CRF 7Q ( 2” deeper than OEM ) was ok to all BB Mopars but not the Hemi before.

I did ask NHRA, so they has now approved it.
But I did also ask NHRA on a Mopar oil pan as they say on the ‘field’ a 8Q race pan is legal, as it has a Mopar part number.
Many seems to use them and speed shop I will use say they is ‘legal’, but NHRA tech told me, it’s not legal just as they has a Mopar part number
Only a oil pan that are listed or OEM is legal.
-So question is ; What to do here as it seems the MP 8Q race pan do pass tech on the field by NHRA.
Next question.
As a new block is ongoing at this moment, I can get it machined on the cam core I prefer, OEM or bigger.
Again, if I read the rule book it is not allowed, and if I ask NHRA tech it is not allowed.
But out on the field I heard this is consider ok as with babbit bearing it can be seen as a ‘service’, and it pass tech since many years.
Can some help me celar this out ?
P.S. I like to use listed parts and read the rule book, and I did actually get the older MP block listed ok from NHRA just some years ago.
