Hi Everyone,

I'm trying to learn a few things about installing bushing in lifter bores. Could someone let me know what advantages and disadvantages to having bushing installed in lifter bores? This would be on a Hemi billet block build. Is there a difference with the oiling system? Meaning that the lifters oil easier with bushing? Can you run a engine at lower RPM with them compared to without them because of the oil? I got the new improved comp lifters. I read some place that you have run the engine at 1200 rpms to keep lubed it don't have bushings. I know there is a lot of experience on here with engines and was hoping someone could share their experiences. I wanted to run the engine around 900 to 1000 for street driving and 1200 seems way to high. Thanks for any help.
