Where exactly does one find a "burned up junkyard" 6.4L? I'm in!

Real question is what the bottom end of the pull would look like with the stock dual path manifold and what the top end would look like with the front facing FI lid on the High Ram. The LS3/LS7 stuff makes the most top end with front facing stuff like a smoothed LSXRT with radius rods installed.

Also, HOW did the stock mushy pushrods survive those springs?? I'll only use the largest and thickest walled 8620 pushrods with real springs. Not sure it's worth saving $150 there...

Ooohh AND Comp says their conical valve springs and titanium retainers can do 7400rpm with their LST cams and I really wanna hear one tach out. Even more reason to forget the factory 6.4 and buy a 5.7 -> 6.4 stroker kit so that you can run a non crossdrilled crank.
