Rob, that engine will probably have the 241 heads like my LS1 has. Just look at the front corners of the heads for the casting #'s. Be prepared for a disappointment in torque with a stock or mild LS1 compared to a 383. It will be the overall powerband of the Gen III/IV engines that you will notice.
Thanks Matt. How much will a Maggie wake it up?
