yessir it is forged, the compression depends on the heads you put on it, but with my 72 cc l92's it was at 11.4-1, ran fine on 92-93. the pistons are -3cc. the miles on it are around 1k maybe, probably less.

With the right gasket the compression gets better 
10.7:1 if you go with .051
10.5:1 if you go with .060
Assuming those ARE 72cc chambers. The L92's are more like 69cc as cast which would explain his 11.4:1 ratio. It would take some pretty hefty port/polish work to get 72cc. You guys run some LSA heads and get 75cc chambers and you're looking at 10.4:1 w/ .051 gaskets.
I only type all this because I have the same 408 build and have been researching how to drop compression for FI.
Ok, I'm done, LOL

i got 415whp with a 230 cam and the dyno operator said he couldn't get my DR's to stop slipping once it hit its powerband. the torque was as flat as a table from 2000 rpms till around 4500. and it was on a dyno dynamics which i have read puts out low numbers. but it feels amazingly strong.
