[QUOTE="Mortalis5509, post: 516541, member: 2838"] [b]Re:[/b] Like everyone said, 500 on a 5.3 is a tall order without some forced induction. The amount of money it will cost is not worth it when a 6.0 or 6.2 with the l92 heads can get there a lot easier. L92 heads with a little work can do a lot. Call Martin at Tick Performance. They took my l92 engine and made it into a 416 with 13.4 compression. Without roller rockers, port and polish, and other things I'm looking at 630hp range at the crank turning up to 7200 rpm. Bottom could turn harder but I would float the valves first. They know there stuff and present on the ls1 tech forum. When I go back and play with the heads I'll be in the low 7's hp. [/QUOTE]
