It's called an L31. 350 with Vortec heads, sequential fuel injection. It's in the same family as the LT1, but it doesn't have reverse flow cooling like the LT1 has.

Do intake and exhaust, but if funds allow, I'd do a Vortech supercharger kit. It's even on sale at the Superchargeronline store. Here's the link:
