I run the Super Victor port matched to AFR 227's with Holley HP1000 on a 409 cid SBC with a .630 roller. This is in a 3500 lb car w/driver running mid 1.30 - 60 ft. times and easy low 10's @ 130 plus 1/4 mile. Used to run the Vic Jr. and was just not enough on the big end.
Of course I never buy an off the shelf intake or heads without expecting to do some kind of port work.
