I installed the Comp Cam 23-712-9 Xtreme Energy cam (286/294 duration with .544 / .541 lift), Comp valve springs (925-16 395lbs/in), with matching retainers and 10* locks to my stroked 440 (440Source heads).
I am ready to order the hydraulic roller lifters, but have read of different 'issues' (that was the extent of the article) with the Comp brand. I did run a set of off-brand internet cheapo's with a quick (142 miles) failure of two of the slide bars.
I will not be taking this over 5500rpm (street). I am looking at the comp, lunati and Hughes Engine brand roller lifters.
Anyone have experience / preferences with these brands (concerning longevity for this setup)?
Thanks
