I had a 78MM setup on my 408, and switched to a ported 90MM intake. I don't have any dyno sheets to back up any gains, but I can sure as hell tell you that you can feel a HUGE torque difference down low just putting around town.
DO IT.

78 here very nice for stock cubes, but you are definatley in the 90 mm range. Dig around, I got mine for 512.00 shipped with new seals, after a little price matching, so figure the 90 could be had for like 560.00
