Shayne,
my 24v is SOHC, same # of cams, just an extra 6 lobes compared to the 12v

I can afford to give up some low-rpm torque to gain higher-rpm power...
On a side note, I advanced the cams 4 degrees and did some testing last night. Indeed low-RPM power is UP. Mainly seems to be up below ~2500 RPM. Looking at the log file, you can see the rate of increase of RPM definitively fall off at higher RPM... Cruising at 55mph and the throttle was reading ~1%. I had to turn off the closed loop IAC because it was trying to mess with engine speed as I was cruising!
When I retarded the cams 4 degrees I picked up power above ~5500 RPM...
I might try making some 2 degree sprockets some time.
1% throttle at 55 is what you get with twin 80s :P
Lack of torque low down = traction control
One can find 2* offset keys I would think..... Or I'm kinda tempted to hog out the key slot each way and shim it.

It wasn't as bad with the cams retarded 4 degrees...
You got it...
The 3L use a pin to locate the cams. What I did was file the hole oval, then tack weld the opposite side to adjust them.One can find 2* offset keys I would think..... Or I'm kinda tempted to hog out the key slot each way and shim it.
Just send two of the higher LSA cams (same bank) in to get a regrind. That way they match.
we thought about that but it wont work. one drives the dizzy
if you deleted the dizzy and ran coil on plug or something it still dosnt work because the cams are different the way they fit in. sad face
OHHHH good point. Forgot about that. (sad trombone sound)
Are all of the 12v cams the same offset? I know the diamante are supposed to be a tad more aggressive, do they still have the offset LSA?
don't forget that the cams are different lengths in order for the timing belt to line up correctly (staggered pistons/heads) in addition to the 12v having the front cam drive the dizzy
Are it possible to run two front or two back heads, never looked at it.

The bare heads are identical, you can flip them and use em on either side.
problem is that they are "flipped" to fit, so no go
Vee motor guys. Rear bank is closer to the belt then the front head. The distributor adapter housing is what extends the head all the way to the belt. As stated, heads are identical.
