Exhaust
Duration: 266
Valve Lift: .445

Sounds like fairly mild cams. Probably the farthest you'd be able to run without getting interference.

Fonzi · 03-30-2015, 02:50 PM

Yea that was the goal for me. Since 2 of my camshafts were bent instead of buy new stock ones, I went with these.. I dont want my idle all over the place but with some extra up top. They do have a more extreme cam but not what I am looking for

not completely sure to be honest. but did go to the machine shop to verify it was .020 out on the dial indicator

Coheed · 03-30-2015, 09:31 PM

12mm on intake and 11.3 exhaust. Have you done any measurements for static overlap? I do wonder if 12mm is possible on exhaust. For your turbo size it seems pretty good. BTW are these measured at .010 valve opening?

Fonzi · 03-31-2015, 10:08 AM

My turbo size will be going to a gtx3076 or gtx3582.. The measurments are done at 110 degree nominal and has a 49 degree overlap.

Who are you using to build your engine? I'm probably going to go that way in a year or two.

Darryljr11 · 04-04-2015, 11:12 AM

Go with gtx30. gtx35 may not hit peak boost till 5k rpm and unless you wanna make a drag monster with over 650whp its not worth it.
