[QUOTE="duane v, post: 811128, member: 11189"] I have Crower regrinds in my 4V and they are very aggressive. They are a custom grind that was desinged for socaldiablo that I think Shawn can only get. With these particular regrinds you will still be able to use the stock valve train components (springs, valves ect ect) for the lift numbers are at .452. But the advertised duration numbers are at 300 degrees which hang the valve open for some time. Since the idle is very agressive I had to purchase the FMS IAC valve adjustable spacer adapter, its also used on 5.0 engines that run X-cams, this device will help regulate the choppy idle. Also you will need either lash caps that assemble over the valve stem or machined washers that assemble under the valve tappets. I went with a .059 machined spacer under the valve tappet to get the correct lash. I installed my cams while the engine was still in the car and it took me approximately 12 hours to complete the install. If you go with billet cams then you wont have to use lash caps or machined spacers. IMO I llike the idea of the stock hollow cams, they are considerably lighter than the billet cams and cheaper...DA snake Boy!! [/QUOTE]
