I have been pushing street car boundaries for years with a big cam and cubes, except I am only at .750 lift in a 605 Hemi.....But even there, it has its price.

New Titanium lash caps every year cause they mushroom....Really have to keep an eye on the pushrod tips and oil spray...I used to burn up pushrods all the time. ...Hot springs is another issue...You have to have enough oil on the springs to not eat them up as well....A big pan and pump are really necessary when doing this.

I have eaten more valve train parts than most race shops over the years..A wedge would be way better than a Hemi for big cube street engine.Preferably a Predator head on Hemi block...

Good Vid
