From my understanding, the 99 & 2000 year, was a 275 hp 2 valve V10, but only had 4 threads machined in the aluminum heads to hold the spark plugs in.
In 2001, different heads were installed/updated & included more threads to hold the plugs in.

2001 hp went up to 310.
In 2005 the new model V10 was three valve heads & hp went up to 362.
