KillaZ, Did you post the same thing over at ClubSi? Funny you got the same answers there that you did here, and they are import guys
The 12.8 was with a different CPU that controlls RPM shift points, timing and fuel delivery. I still say that the 32v 4.6 and the LS1 are equaly impressive motors.
And you are right about LS1's killing 94-95 5.0 Cobras. They typicaly run low 14's but I dont think justjoe's is stock.
