I wouldn't touch a V8 SHO engine with a 10ft pole...
They have serious cam problems that destory the engines...
I know...I had a 96 V8 SHO that decided to grenade on me at idle

also finding one of thoes engines is a needle in a haystack because of this specific problem...you'll pay for it...I've heard of USED V8 SHO engines needing slight rebuilds for 5-7k
