Lunati Voodoo 703 will be too big for that 2400 converter. That gear will kill it too. Go with a 3.55 gear or so with the Lunati Voodoo 703 and use a GOOD 3000 stall converter. I have one right now with a 3500 stall and it's a hell of a lot of fun and very drivable. If I take it apart again... hope not... I will try a 3000 stall. Any 268 grind is iffy with that combo. I have tried different "268" cams with 2400 stall convertors and they are just to tight. Converters have came a lot way in a few years. Don't be afraid to let that engine get to the cam.
