The model number is IT20TT. Some parts catalogs only use the part number 4714. It is the same heat range as the OE spark plug and has a tapered seat which is a universal fit for all LT5s.
This is an expensive high mileage spark plug, good for at least 40k miles. I agree with Paul that the dirt cheep ACDelco 41-602 works great for 10k miles.
