Another concern that you may have is the compression ratio in a stock 454 LSX crate engine is 11:1, not real FI friendly
Also, the cam maybe not the best for a boosted application
I would recommend contacting one of the manufacturers that Will mentioned above (ie Kenne Bell, Whipple, Magnuson ) and see what their techs have to say about the compression level and cam specs
You may be ok, just by running a lower boost charge??
It would really suck to shell out $12k for a new crate engine, then have to open it up to change things
You could also look into one of the many quality engine builders to build exactly what you want??
Most offer some type of warranty too
If you buy the crate 454LSX and open it up, there goes your warranty anyways
