WTF?! what motor mounts for a 69RS with a 454Big block?

Hello all,
I have a friend that is having fitment issues trying to swap in a mid-80's big block 454 with moroso oil pan. into a 69 RS camaro. What motor mounts/Frame mounts should he go with?:confused:

We have already tried, 427 BB 69 motor/frame mounts- from left to right the pins wouldnt line up, and moroso pan was bottoming out on the crossmember.

one other note is we would like to keep useing the stock cowl hood, so fitment is critical. :cz28:

My neighboir and I just dumped a 468 in his 67. We reveresed the small block right and left side mounts and it worked.
Worth a try on yours!
