Tho owner says same cam, same ICL.


He kinda says "everything" is the same, but never specifically says the cam is installed at the same c/l.

Plus, no cranking pressure test for either set of heads.

It's a pretty long thread over there, lots of info to go through.....
I know it's a Bullet cam...... And I thought I saw it was an UltraDyne grind.
If it's the old UD .4176 lobes...... Those aren't really "tight lash" lobes, and I see on the dyno sheet from the original post they had the lash at .016/.018.
When I ran those cams, I used .026/.026.
Might have helped perk up that missing low end TQ.
