    Me too, a lot of work and money by the time you get done, I hope it is worth it.

      Don't expect big gains with this mod, it is just an excellent option when upgrading your rockers.

      Not very difficult or expensive in the end.

      I have pictures of a mini shaft installation but they will not upload here

      How small does a file need to be here? I resized to 331kb

        Agreed rollers are small gains generally WOT high rpms.

        Far as pics. site doesn't allow uploading pics.
        They need to bo hosted elsewhere and linked.

          more lift,quicker ratio with no effect on duration. plus a cheap way to get rid of the wore out flimsy and in precise stock rockers. looks like a win to me.


          how much lift is lost on flex of the flimsy amc rocker bridge? i've seen a lot of these that were bent and rounding off the top of the valve. no wonder the guides are always so wore out on these.



          put these on a elgin industries CL912 cam kit and it'll pull hard off idle and rev out well past 5 grand. which means in your automatic equipped ride it'll pull from off idle to shift rpm.

            Yep. dunno how accurate 1.6 is on AMC stock rockers?
            Lots of stockers especially Chevy aren't good.
            Supposed to be 1.5, VERY few actually are.
            They also vary quite a bit...
            Might not be an issue w/ AMC but it is on others.

            Like I already stated a couple times...
            Don't care about hp gains
            Don't think it's a bragging point "I've got rollers"

            For me it's about the added lift, stability & consistency.

              the lift ratio changes thru the arch with standard design rockers. roller rocker maintain it thru the arch. thats where the gains are.

                I wonder if there would be any noticeable differences on a most stock engine, as far as power and driveability.
                But a slightly more modded engine (bored out, aftermarket cam, headers, intake, etc..) I wonder if it might be slightly more noticeable.

                Keep us updated on how things go.

                  So I cannot find my adjustable pushrod...

                  Doing the math 18 tpi is .056 @ 1 full rotation?
                  Which means to obtain .020-.030 = ~1/2turn(.028) after zero lash?

                    If you can not find a set of bolt in pushrods, then you will have to have set custom made. Maybe the Harlan Sharp, Comp rollers might be worth a look at? I used small block ford comp full rollers with 1.7 ratio in my race motors

                      These are bridged non-adjustable rockers. Simply trying to get a preload measurement.

                        Correct

                          Yes, your math is correct.

                          LS1 rocker puts the pushrod seat .040" lower than the AMC rocker from my '90. The AMC rocker ratio measured 1.605, LS rocker 1.715. That's just straight measuring the rocker, not the actual valve lift vs lobe lift measured with a test spring (my engine is still in pieces).

                          I'm going with the summit K8600 camshaft kit which as .080 smaller base circle on exhaust, .050 on the intake. So I may be able to reuse the factory pushrods on the exhaust and compress the lifter .015 more on the intake.

                          But the heads, deck were touched, different brand lifters, who knows how the head gasket thickness matches the oem, so I'll find out when I assemble.

                            Curious if anything came of this, or has the project been shelved?

                              My engine is together with the factory rockers and pushrods, just changed the oil after break-in. I'll get to swapping in the LS rockers eventually.
