Roller Rockers w/ low valve covers - grumpyvette or anyone else know this.

[bigbore468]

Do you all know if there is an aftermarket roller rocker arm that will fit under low style early SBC valve covers.

 

My issue is that I can't run the tall valve covers due to the A-6 A/C Compressor being mounted on the top left side of the engine; relocating this will not be an easy task...

 

Thanks for any feedback.

Cheers

sure, this type USUALLY fits inside many stock valve covers,naturally youll need the BBC version if its a BBC and the self aligning version on a SBC VORTEC HEAD

but you might need to get differant adjustment nuts as those might be too tall for some valve covers, I know they fit on most corvettes stock covers AFTER use of a DIE GRINDER to remove the DRIP TABS on the inner valve cover surface

Grumpyvette,

 

Thanks for the reply.

Will probably go with the Comp Cams Pro Magnum roller rockers for generation 1 SBC, as they look like they will work with the short style polylocks.

I got aftermarket steel valve covers, so hopfully I'm not going to run into the problem with having the locks hit the top of the covers....

I know exactly the problem you mention with the aluminum Corvette covers.

Not sure if this is relevant, but on a BBC the Comp Magnum steel roller-rockers fit under a stock-style (short) stamped valve cover if you use thick (3/8") valve cover gaskets. It may be similar on a SBC. Of course, it also depends on the height of the heads' drip rails. I have Brodix Race-Rite heads, which are notorious for short drip rails.

I ran the crane gold race rockers under stock steel valve covers. You have to clearance them with a ball peen hammer unless you use the short locks. You might use two gaskets if you have clearance with the AC.

Thanks for the reply guys.

Looking at using a stainless steel roller rocker arm with short polylocks, and Edelbrock stamped steel short valve covers.

I think the Edelbrock valve covers have a little more clearance vs. the stock GM.

 

I'm running a stock GM long style water pump, brackets and pulleys that were used on 1968 through 70's passenger cars, no power steering.

 

My Hybridz is a 1976 280Z Coupe.

 

I would not drive the car as much if it did not have A/C; so maybe some of you that have A/C with the compressor mounted on the driver side can post what model compressor and brackets you used.

Cheers.
