THe firehawk has a solid 408..exact specs unknown, atleast to me..lol
The sc camaro was rumored to be a 408 and a d1sc..however word on the street is now that it is a forged 6liter(lq9) with unported 317s/built tranny(m6)/9 inch with 430's.. I was told all this second hand so might not be entirely accurate..hope this helps..
2001 Z/28: Just a 347 and a D1sc
2009 G8 GXP: Modular Society 22s/varam cai/Fast 102/kooks/corsca
2008 TBSS: K&N FIPK, Slowmaster muffler, lowered 30.5 all around.
