Jun 272 plus STi V7 valvetrain
Can I get away with the Jun 272 cams with the stock STi V7 valvetrain?
I have a EJ257 shortblock in my WRX and I don't plan on reving over 7,500 rpm.
TIA

No, You can run 264's though, JUN *cautiously* says it's ok. For the 272 you HAVE to have dual springs.
Honestly, if your going to drive the car on the street daily I would recommend against the 272. Vacuum is about have of normal at idle and they really don't come on line until 63-6500rpm But the 264 cams have a really broad torque curve and only have .8mm less lift than the 272 cams.

Get some 264s and be happy. I wonder who sells those JUN cams?
