update (no charts) LOST at least 35whp
total disaster, well almost. lost 35whp from last time. this was the process i used....
started on the small lobes only. resulted in a very nice flat torque curve to about 185-190ftlbs and whp reached just over 206. afr's were good (mid 11's), timing peaks @ 25*. gained LOTS of torque down low compared to the N1's
so now i introduce the intake cam. i start at 6k swich point and work my way down. every time it hits, power climbs faster like it should. but the result is not a increase in peak power. so i figure the exhaust cam still being on the small lobes is the reason. so lets set the exhaust cam to a few hundred later than the intake cam like i've always done. fucking bullshit! significant nosedive when the exh cam hits. nothing i did could make the power continue to climb like it should.
i HOPE it is the exh cam being set @ 0 thats REALLY screwing things up, but i have a hard time believing it.
so next week the slide type cam gears go on so i can do some street tuning to try and figure this shiiet out.

lets look at the changes made since last dyno:

the header now has a 2.5" choke instead of a none. it was just a straight 3" after the last merge.
new vibrant resonators VS old 18" body dynomax.
cams were changed from N1's set at +3/-2 to 184c V3's set at +3/0.
new cap and rotor
new ngk bkr7e's gapped to .035 VS the old bkr6e's @ .032
new bc valve springs VS old bc springs
a little machine work done to the pistons for more clearance on the headgasket.

think thats it. help me out here guys. could the exh cam being set at 0 screw things up THAT bad? sorry, i didn't get a copy of the chart i was like TOTALLY pissed/disappointed/embarassed:o

Why are you separating the cam switch over?

now correct me if im wrong here guys, but wouldn't you normally start with the cams at 0/0 ?

yes most people do to get a baseline and adjust from there

Unless they changed their centerlines for the v3s the exhaust cam should be pretty good at 0. Sucks to hear, hopefully you get it sorted out.
