pictures...from me. lol. don't have and know how to use a cell phone. have to get the kid to do it. i can easily build 1.7 non adj rockers. knock out roller bearing and ream it to fit the shaft. adj p/rods req. yuck! may knock out the socket and drill/tap for stock p/rods. the only alum i've seen has been 455 and the rest were sloppy joes. had 2 set of rollers for stg 2 v6. huge suckers. sold them. have 2 different sets of reg v6 rollers. no names. 1 set for 350. hopefully this new project works out.
If you take the bearing out and ream for the shaft will you have to put a groove inside the rocker so it can get plenty of oil between rocker and shaft? Well, nobody does what you do so I say go for it and see what happens. I had to buy all new bearings for my roller rockers and new shafts as those bearings from old rr's were digging into the shafts especially at the center rockers on both sides. The new bearings have the rollers tighter/closer in the cage now as my old ones were not. I was able to get the bearings from a place we do printing for locally, they were the same bearings TA sell. Going for the 8's this year?
the non adj i just reamed the hole to size. but still have to make it adj. groving not a problem. bearings, not many choices. but you need the meat around the hole to use .812 bearing whatcha you watching dana ?
i took apart the adj rkrs. needle bearings all over. guess 2 x 16 x $10 = $320. ouch! bearing number is B-96 or 16 of B-912, $160 unless forego the bearings, ream them out to .812 and be like buick oem. which way do i go. bearing od is 3/4. put rkrs on shaft to see how close they fit the valve/p/rod. damn close. the non adj, 1.6 & 1.7 also look good. only problem they are stud rkrs = wide. have to side cut them and rkr stands. have to look at whats out there
duh on my part. 1.65 to 1.7 increases .020 lift. got to look at the spring compression gap. rkr mounting...open hole to stock .812, like oem alum or make new shaft, bushing, collar and bearings terrible being an r&d/exp machinist. i look at a million ways to do something. ugh.
Bronze bushings, swedge them in, ream and forget abt bearings. You don't need bearings cause the rockers are at zero rpm.
I thought the same thing and I know we talked about this in the past use a bushing in there with rocker. Yeah zero rpm on rocker they will only wear out on the bottom anyways. Then change out that bronze bushing each year.
Just like the early stock aluminum rockers, no bushing required. Aluminum is good bearing material. Clearance of .015 would be good. Pushrod oiling goes right to the fulcrum. Those roller rockers are designed for pushrod oiling. Jim Blackwood is doing something similar: BritishV8 Forum: Adjustable rockers for the late Rover (rollers?)
So if gsjohnny just reams out the rockers to the Buick shaft all should be good if the aluminum can hold up to wear. If this works we can all send our Ford roller rockers to johnny for a fix lol. I looked at what Jim was doing and can't see why this will not work, unless drilling out the Ford rockers will make the rocker too thin.
350 shaft is .812. sbf hole is .750. reaming to .812 is not an issue. could even move the hole around(that's work). mulling it over, going to just ream the holes to .812. may have to drill a hole on top thru the rkr for oil just in case. still have to make spacers to hold the rkrs in place OR that thru hole on top, slot it for a locating pin instead of spacers. maybe it will work.
How abt leaving them alone and get ground 01 stock and shim the pedestals. You could space rockers perfectly. Ford shafts solid or hollow?
need a length of .562(?) hardened and then make 6 of .812 collar stands to fit over the .562 and which way do i go to locate the rkrs? do i make spacers like are on some of the rllr rkr setups or cut a slot in the rkr and use some sort of pin? i've gone over numerous ways in my old feeble mind on 'which way did he go'. forgot, when the sbf rkr shafts come out and those little needle bastards fall all over the ground, i will have to but 16 or 32 bearings for the rkrs. looked for bronze/oilite bushings to maybe work. nothing yet. ideas???
I'd go with spacers between rkrs for spacing.. Collers with i.d. at Ford rkrs i.d. size, Buick shaft o.d. size, with thru bolts to pedestal mount them. Throw the needle bearing in the trash....
I'm dealing with a set of Procomp 1.6 SBC rockers but what I've learned is that you have to look at not just the ratio, but the distance from the roller pin to the fulcrum centerlines AND the side offset. Getting all of those right is tricky and even offset boring the shaft hole isn't quite enough to center the roller on the valve stem tip. Closer, but not perfect. Probably close enough to work but could cause guide wear. Obviously it isn't going to be perfectly centered all the way through the valve lift. As for side centering, a little offset could be fine as rotating the valve is generally considered a good thing. Some engines even put a thrust bearing under the spring to let the valve rotate easier. Jim
i've read thru it, i forgot which brand has facts/figures on their rocker arms on line. damn crs. what we called back in the day. mfg r&d..... you think you know what it means. really means 'make a f...ing guess, run and disappear'. works every time.
have 350 1.65 rollers have kb v6 rollers have another v6 rollers one of the v6 is 1.65, the other unknown don't recall any of them offset. have to look
