Should work well, install it advanced to help with the glide. Use a very loose converter if you have the option on stall, 5500+. With a loose converter, a 500 inch 440-1 motor will run well with durations up to 284 @ .050 on the intake, and if the heads have been ported, all the lift you can muster. My best results have been with a roller of 283/296/110 with .775 int .680 ex. although I do have more cubes at 528.
