the street dominator was intended for 273-318 engines that had low hood clearance and needed tq. The perfomer and street dominator would probably be a toss up so use what you got. Either of those two intakes will bolt up and run on a 340-360 but be down a little top end power.

The strip dominator on the other hand is desighned with the bigger 340-360 ports and will make good top end power on those motors but they tend to kill the tq a little motor needs.
