I know a few of you guys have upgraded to 1.7 ratio roller rockers. I found a set of roller-tip rockers on ebay for about $70 shipped. Is the difference between full roller and roller tip worth the extra expense?

Full roller, the only benifit from those would be that they are 1:7's.Chris - A 20th Century Man \m/ ^.^ \m/ -
I like that style, but those particular ones are for a Chevy:
Do they have them for SBFs too?Comment

Those are Chevy? Chevy engines don't use a pedastal type rocker. They're fully adjustable, and you have to set each rocker to the proper preload otherwise it doesn't work. There is a whole sequence to it, and I don't see how you could possibly do it with that style rocker unless it was converted to pedastal. Chrysler uses a rocker shaft arrangement but its one shaft per head.86 Lincoln Town Car (Galactica).

the differene bewteen a full roller and a roller tiped is that A roller tip helps to minimize a bit of friction on the tip, but still rides on the big saddle. a full roller rocker rides on needle bearings.http://secondhandracing.com/Home.aspx

Duce, are you replying to me, or to Nitroracer? Cause I was interested in the difference between the pedestal-mount and the stud-mount full rollers. Also why does Thain imply the Vortec rockers from the pic above are for pedestal mount, while Scott says just the opposite? I'm confused...Comment

Pedastal mount rockers you just tighten down. They have a piece under them that prevents the rocker from being run down too far. Its kind of a pre-set deal. Stud mount rockers just have a nut pushing them down. You can run them all the way down and keep the valves open if you want. They're fully adjustable.
This is an FMS 1.7 roller rocker. Note the small piece over on the right. The flat side sits against the head, and the cupped part sits on the rocker arm's pivot shaft. The head has a tapped hole for the bolt to thread in to.
This is a Chevy stud-mount rocker. Note the lack of bolt and pedastal thing. This just sits on the stud and uses that locking nut to hold it down. The lock nut has an allen key inside that you tighten to jam against the stud to hold it in place.
This is a Chrysler rocker shaft setup, probably for solid lifters since it has the valve lash adjuster screws.
I still say I don't understand how those mini-shaft deals would adjust but maybe they would. Probably could do it with a different torque sequence than the standard seperate rocker type uses. Just do it one cyl at a time as each comes up on TDC.86 Lincoln Town Car (Galactica).

Nitro, for about 10x the price you can step up to full on all out race rockers and get a Jesel shaft mount set up.

Oh, okay, I get it now. So I'm looking for a 1.7 pedestal-mount full-roller set... aluminum or steel rockers? Ebay has both, price is about the same.Comment
