depending on the year of that Caddy, it's probably an LS2Are ya'll talkin about LS1s?
500 would be a stretch allmotor, even with heads and cams and every bolton imagineable
You can keep your engine stock and throw a 200hp shot on it and make 500hp....for less than $1000:yumyum:
It shall be my next "impluse buy"
which with just a L92/L76 swap will be close to 500 hp
