Any dyno numbers yet from anyone on using the 290 deg duration, 11 mm lift EX cams on a stock GT head with stock GT INT cams with longtubes and Boss intake? Highly interested in this combo :rockon:
What do you think about the MMR tensioners? Wont they help solve the deflection issues?
If the exhaust cams get more and more retard due to a slack chain that's not quite as bad at high rpms right? isn't the ideal centerline on the exhaust of an NA pretty high? ie. 112 or more.
I know some folks on yellowbullet said they leave the exhaust cam parked to work properly with turbos. now clue why that works.
