My primary failure was a rod bearing, that's what was making noise and best guess indicates a detonation precipitated the impending failure. Pulling it apart we discovered (so far) a broken ring and a chewed up cam. Previously it was an AM spring that popped. Unless I'm forgetting something, nothing OE in the valve train failed or even looks tired.  It's not a lot of money difference, so that's not my concern here, but spending a few hundred dollars extra for nothing more than a little more valve train noise in reality doesn't appeal to me either. |
I'll say it again, you're not going to a solid roller, you're staying hydraulic, noise should not increase at all. My injectors are louder than the lifters are, you're having a reputable shop doing the work, so I would expect them to install them with the proper preload and pushrod length.
If a portion of the cam was chewed up, and not the lifters that means the lifter was collapsing at some point and bouncing on the cam or the push rod was flexing. Link bars won't collapse, so no float, etc. Lifter failure is usually for extended consistent RPM, usually doesn't matter at what RPM. 20 seconds at 4k is riskier than 3 seconds at 7k.
I'm all for saving money, but, the valve train is not the place to do it. So either run a cam that will match with the LS7 parts, or run stuff that matches the larger cam.
I'm just offering advice, you can take it how you please.
