Title says it all, just checking to make sure.

Thanks.

I believe they can but require a different size stud. Search should turn up the answer pretty quickly.

Don't take life too seriously -- you'll never get out if it alive.

yes, they CAN. like mentioned - you need to replace the studs.
also - some may not physically fit.

You've got to get narrow body rockers. Also, of the ALUMINUM narrow bodied rockers, I've only found 1.6 ratio as the highest.

Crane sells stud adapters to use rockers for 3/8" studs. I have these on my heads with Summit 1.6 Aluminum Full Roller rockers. They look just like Crane's only in Summit blue color plating instead of gold (Crane).

I didn't want STEEL rockers as I was looking for a light valvetrain...

Thanks guys, thats a lot of useful info. I appreciate it.

A set of lightweight lifters and pushrods would do you infinitely more good than aluminum over steel rockers. There is very little momentum in the rockers compared with the pushrods. (Althoough the bearings between ball rockers and rollers makes a significant difference)

Just saying for those of you who want a light valvetrain because it shouldnt begin with light rockers.

Remember that your SBC studs are a different thread than the Fiero studs and you'll be setting your valve lash similar to the SBC valve lash adjustment.

I am using roller lifters so no optiond there. As for pushrods, I have custom sized ones to take into accout the difference between the roller lifter and the rocker. Those can be lightened...I'm just wary of aluminum pushrods.

I suppose you could try out a set on the intake side to see if they last.

I didnt know you needed a custom length though. Learn something everyday.

Yes, but SBC rockers use 7/16" studs. 3/8" studs are for Ford SB engines.

Fiero heads use 10mm studs. SBC's use 7/16" studs.
You can get adapter studs that have a 10mm side to screw into the head and a 7/16" side to hold the rockers.
Or you can have the heads drilled/tapped to use the 7/16" studs.

The Summit lists both Ford and Chevy both using 3/8 and 5/16. It would probably depend on the heads themselves and has nothing to do with the block.

@AP2k
I'm using a 3400 roller cam block. Hence the need for roller lifters and custom pushrods. I use the term "using" loosely as my car is being held in a mechanic's lein by the idiot grease monkey I was paying to install the motor, who refuses to finish the job, damaged my car, and expects more money from me.

Stock SBC/BBC = 7/16"
Chevy inline 6's use 3/8" studs.(These are where the narrow body roller rockers that Crane has were originally designed for.)
Crane Cams does make a specialty set of Gold Race Roller Rockers (narrow body) for the Fiero 2.8L that use the 10mm bottom/ 3/8" top studs which is required.
2.8L kit with 1.5 ratio =
http://www.cranecams.com/?show=browseParts&lvl=4&prt=108&action=partSpec&partNumber=25750-12
2.8L kit with 1.6 ratio =
http://www.cranecams.com/?show=browseParts&lvl=4&prt=108&action=partSpec&partNumber=25759-12

But the question of this thread is "Do SBC rockers work on the 2.8L"? A standard SBC roller rocker will not fit on the Crane 3/8" stud adapters.
I think this is where the confusion seems to be.

Ford used 7/16" studs back in the 60's and 70's. In the 80's the 5.0 (and other V-8's) went to 3/8" studs.

Hope this clears up the confusion.

awesome, more good info

now I found these:

http://www.flatlanderracing.com/scorpionrockers.html#chevyNarrowBody

" SCP1088 Chevy V-8 305-350, V-6 262 1.6 SBC 3/8 Narrow Body Rocker Arms (V6) $149 "

It says narrow body, it says SBC, and then it says V6? Could these work as well? I'm assuming it doesn't come with the stud adapters and I don't even know if they're roller rockers or roller tips or neither?

They are probably steel. Again, I wanted specifically aluminum w/full roller. The adapters are JEGS p/n 270-99148-2
They come in pairs so you need 6 pairs. I could swear they were cheaper when I bought them in June...

Also, the Crane rockers are always on back order so I ordered these: SUM-G6936-16
from www.summitracing.com

Funny, I switched out the 3/8 studs in the Edelbrock RPM heads I got for my 350 build, to 7/16. They are bigger. Do not see how going from 7/16 to a 3/8 stud would be an upgrade. I think you've got it backwards. All stock SBC's I've worked on were 3/8 press in studs, which again, is smaller then 7/16.

Yes I got the "Upgrade" backwards. I removed that statement.
Edelbrock makes the heads with either 3/8" or 7/16" studs it depends on which way you buy them. But these are not stock GM heads.

I know, the Edelbrock heads were not to compare to stock.
I was pointing out though, the Small block Chevy, form the late 60's, to the late 80's use 3/8 studs in their stock configuration, not the 7/16 as you had mentioned. Thought you might want to fix that misinfo as well.

Kevin

Or maybe not.
