I have read two different posts on ceramic lifter failure, and it would be hard to judge what caused the problems.
I am going through the motions with a leading engine builder sorting out 427 engine makeup and what scares me is if something fails prematurely I might not have the cash to fixit.
My builder recommends a Solid roller mild camshaft with .650 lift, from what I can gather roller cams have better torque etc, and as I am after over 600bhp with either a 450 cuin, or 468 cuin engine, I would prefer to stay flat tappet with the best quality lifters and change them all at say 20,000 > miles, but I guess there is more driveability and power with the solid roller. I read these horror stories of roller lifter failure, but one aspect with the needle rollers in the lifter is it never really stops and gets an impact - normally!!
