Crane Gold Race Roller Rockers on 3400

[AaronGTR]

I wouldn't waste the money on the gold races. The 60 degree performance maual shows how you can use bb AL rocker arms from crane and they are only like 150 bucks. any thing from 1.6-1.8

I wanna know what you're talking about too. So far no one has found any rockers higher than 1.6/1 ratio that they can verify will work on gen3 heads. There's only been guesses made.

First if you are talking about energizer rockers then they are not equivalent rockers. They are die formed aluminum. Secondly a BBC rocker is HUGE THEY DO NOT FIT. Read the article again. It says to install 7/16" BBC STUDS. Then use 7/16 narrow body aluminum rocker arms for a small block chevy. The BBC stud to stem distance is not the same as the 660, and the rockers will not work. Third no matter whos rockers you buy they are going to require conversion studs which is a reason the 660 set is more money than a SBC set.

Here's a thing I've been working on for the Gen3. Bolt, roller, roller axle and bearing are off the shelf items, the pedestal, the main axle, and the body are special.

I know this may be a long shot, but what if we took a petition and submitted it to Crane and Comp about having them make rockers for the 3rd gen engines. I am sure it wouldn't be to hard for them to design.

Sorry I regurgitated the wrong info. You can use the AL rockers from a SBC and yes you have to change the studs, BUT if you use the ball type you don't have to change anything. There are two options for changing the studs...you can have your heads tapped or you can buy the conversion studs from West Coast Fiero. The manual explains it better than me. Sorry for the misguided info...I really try not to do that.

Those gold races are still a waste of money. $400 for AL and 1.6 never I there is no way to justify that cost no matter how you slice it.

I drive a 3.2 fiero. I have the iron headed 60/V6 from an APV. I know about fieros and the iron headed 60/V6 2.8-3.4.

It is funny how nobody knows about this manual (It is in the PDF downloads).

The reason the rockers are so much is because they include the studs. They ARE pretty much a bolt on for the 3X00. For the Iron heads and the Gen II they are a direct bolt on. I never paid $400 for mine. I paid a bit over $300 and that is Canadian Dollars. Look at a competative rocker and Cranes pricing is right on par. Also the studs can be bought from Crane or ARP. So in actual fact you can buy anyones narrow body rockers and use studs from ARP. If you are going to tap the holes to SAE thread yourself then you must use a 7/16 stud because the 10mm hole in the head is already larger than a SBC 3/8" stud.

If you are looking at pricing from West Coast Fiero then no wonder you think they are so expensive.

Bringing this one back from trhe dead.....

We've established that the gold race rockers are basically a SBC rocker, right? The biggest issue is a slight clearance problem with the "tail" of the rocker hitting the underside of the LIM.......has anyone looked at Crane's gold race rockers specifically for the LS1/LS6? They appear to have a narrowed tail section that may work without needing to modify the LIM.
Also, side benefit of 1.7:1 or 1.8:1 ratios.

Discuss.

[bszopi]

Its been discussed (Apr 05).

I didn't read through the entire thing again to see the outcome, but IIRC there was an issue with the location of the pivot point in comparison to the valve tip that made them not work. Although the LSx engines are SBCs, the heads changed, so normal SBC stuff will be different.

[geoffinbc]

Agreed the LS rockers dont work. Too bad because they come in some nice ratios.

[MidnightriderZ24]

does anyone have pictures of the rockers installed and the LIM clearanced?? so pretty much i can just pick up some sbc rockers... cool

[AaronGTR]

If it's been determined that the crane gold race roller rockers are just a narrow body SBC rocker, then shouldn't there be a SBC rocker available in chromoly with a roller tip instead of aluminum? With the smaller nose possible because of the stronger metal we probably wouldn't have to clearance the LIM anymore and the crane gold's would be pointless.

I know this has been discussed before, but I couldn't find the rockers that were referrenced, and why hasn't anyone tried them yet? It would make the full roller swap so much easier, and possibly open the option for 1.7:1 rockers?

[geoffinbc]

Only Comp has the narro body rockers in Chromeoly. But the problem is they are all self aligning rockers. You could easily grind off the little ears to make them work and use pushrod guide plates.

If you are thinking of using self aligning rockers on the 660 well you cant. The ears will contact the spring retainer and ruin the parts. There is not enough valve stem tip sticking out past the retainer.

Here is a page listing all the types of SBC narrow body rockers. The article is for a 4.3L V6 but the principals apply. http://members.shaw.ca/betterthanyou...llerrocker.htm

[gectek]

what about some of the pro magnums that comp has, ie 1318-16 for the self aligning 1.6 and the 1302-12?

would the only prob be that the pivot is too wide?

or some of the high tech stainless rockers 1102-12 for 1.6 and 1103-12 for the 1.65

also comp has a 1.65 alum full roller, just like the ones from crane p/n 1003-16
