Solid roller lifter failure

Money an issue? Flat tappet cam is cheaper than any roller combo.

Ernie, had we not gone through the bad metal/low zinc scare of about five years ago we wouldn't be having this thread. You would only run solid rollers if you wanted to eke out the last little bit of power and you didn't mind replacing your lifters every so many thousand miles (usually because it's a race motor and you have other components that require replacing as well). Everybody knows that, but it's the customary tradition of this forum that once you've established a position you stick to it and don't budge -- especially if you've put that particular part in your own car. There are exceptions to that rule of course, but they are generally limited to members who know how to correctly spell the word "eke."

True, you have to stay on top of maintenance with larger solid rollers. Looking back at my records, I replaced 3 sets of valve springs and nothing else in 6,000 miles (2500 track miles included). And, I was running a much larger roller than Berm, his roller is mild by comparison. With proper components and maintenance his combination should be bullet proof.

Eke? That would be great effort for little result. I picked up 50-60 ft/lbs over the most aggressive hydraulic roller with no loss of drivability. So, "eke" would be inaccurate based on gains alone.

I'm just making the point that Berm should be able to run his cam without much effort and continued expense, if that's what he wants to do, based on my experience. To say that everyone should run flat tappets, well... that just sounds ridiculous coming from someone who knows how to spell such big words.

I should also note that I no longer run this motor, I 'budged" to a modified LS7...
