Difference between the LS1 and AMC pushrod cup is ~.040. LS is lower. I will know if there is an extra .040 worth of compression in the hydraulic lifter after I get this damn engine together.

I can't seem to upload photos here. Too new?

Nice...what installed spring height are you working with?
Seems they used 2 different heights, which obviously effects things.

I was at 1.800 before cutting seats and valves, which is when I did my stands. Oops. I'm now at 1.830 and may shim the stands a little but probably not, pattern still looks better than the factory rocker (which is not saying much).

I'm working with a 1990 AMC 360. Fixing a timing cover bolt hole oil leak lead to noticing .110 crank endplay, which lead to finding wiped out lobes (truck ran great honestly) and 2 scored cylinders. I was playing with some LS rockers on my desk while waiting for the engine to be bored. I paid $50 shipped for a clean looking set off ebay.

I should start a build thread.

Cannot beat that price.

I just ordered a set with trunions installed for a 360 build in the near future. I have been using mini shaft adjustable rockers but decided to go back a torque and go factory LS rocker for this one.

I will post when I get into it

This seems very interesting. I will be watching this thread closely to see how it works out for you and what, if any issues you run into.

This is a great looking upgrade. I need to dig thorough my extra LS parts and see if I have a set of rockers sitting around. My 76 J10(401) needs all the help it can get.
I would love to see a before and after dyno sheet to see what the gains really are. Similar to how they test on Motor trend "Engine masters" show.

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.

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.
