The simulators always seem to show more power with a wide lobe sep. But the track shows different. Maybe some go by simulators, others by et.

Results speak louder than theory, correct

Is LSA not a result of valve events rather than the other way around?

IMO everything has to be taken into consideration but as a combination requires more duration generally would seem LSA would get wider so overlap wouldn't get out of hand.

Or, another way of looking at it is, 112 lsa with 230 @.050 or 280 @.050. Overlap quite a bit different

The highest depression occurs during overlap. I think 2 valve wedge race engines like that.

With my early data being incorrect, I have the degree wheel correctly zero'd and now using my lifters for measuring as Bullet says its more accurate because of the roller wheel. Dwayne was correct about the lobe lift at TDC being in the area of .150, I now measure .154.5 and that looks to be right on with the cam in at 105. I'm still trying to figure the duration at .200 lift. The open close points look to be where they should as well on the intake. Once i get the head back i'll check with clay and again with checking springs. Hope to get this back together asap.

If the cam card says the duration at .200 is 190 degrees then that means the two points should be almost straight across from each other on the wheel. So just pay attention to the point where it opens to 0.200 and then note the location where it hits 0.200 when closing. The two points should be almost straight across the wheel from each other.

Thanks Andy
