Ok guys, I need some advice. Should I go with comp 850 or 875 lifters? Have stock bottom end (not going to rev high), no or rare drag race, revs below 6000. I will be installing vortec's and comp 415 cam. I've done lots of searching and reading, and as far as I can tell, the 875's are a better lifter design, but may make a bit more noise than stock. The price difference is not much between the two, if purchased new. I would prefer a "sleeper" type of vehicle, but want a reliable driver. Rest of my build can be seen in my signature. As far as I can tell the 850's are close to stock (which works fine now), and that may be all I need. Any advice?

850's are fine for most application. I took mine out and went with 875's when I changed to the 422 cam and they are considerably noisier. With that said I have a good set of used 850's and a comp 412 cam if you are interested.

I think I have decided on a comp 415, but thanks for the offer. Best I can tell, they are pretty close, with the 415 being a little more aggressive and mid range oriented.

The 415 is a good choice but if you're going vortecs and buying a new cam you should consider the 422. That cam will compliment the vortecs even better and its not too aggressive. 875s are a "better" lifter but not needed and they are louder like I said. Wouldn't hurt to go with the 875s but the 850s are slightly better than stock and sufficient enough.

i'm intrested in the lifters, 850's being better than stock, i think they are just repacked OEM GM''s
i had 2 sets of 875's and hated them, my fatsest truck has stockers, and do the job just fine.
