Is drive the street with that cam. Looking at the duration @.050 and not getting overly scientific and split hairs over the specs, this cam is in the same area as the MP 296/.557 cam. The Purple cam normally works out to be a 252@050 cam. MP suggests this cam for the 11.5 second zone. But the Hughes cam has a nice mild split duration & more lift to work really well with heads that have a really good full porting job to them. If your car is properly equipped and light weight, I don’t see a problem in obtaining low 11 second slips. Not that it is just an easy bolt in/on and run no brainer.
(Light weigh = 3K lbs. and the proper 1/4 set up in the car. High stall and gear ratio, single plane, etc....)
The duration is stout for a street cam but not a undrivable unit. It’s totally drivable. You’ll need some gear and converter though. A couple of fellas here have used that purple cam and a RPM intake to run low 11’s. IIRC, our old member UOP (?) did this with a 360 in an import car.
