R.W. Cams Inc ( Atlanta - GA ) NEED Imput !!!

I have recently obtained a mystery cam that this older fellow purchased back in the 90,s at Mopar nationals and seller could only tell him it was large so guy I bought it from sent it to local cam company ( might be out of business ) and they determined it was ( 704/669 Lift and 286/288 Duration ) with 1.5 rocker and 110 lobe Sep for Bigblock Mopar . I assume this is a solid roller correct ? with so much lift and it is not of cast material . I'm building a 512 with new Victor heads and intake could this cam work ok with my build - thanks Chris Ps I have cam card from company in Atlanta who determined what's specs were .
