I cant seem to find a double roller chain for a roller block. Could someone tell me where to find one.Thanks.

 

Where have you looked? Every manufacturer has one... try Comp Cams 2136.

 

check jegs or summitracing if you cant find it online give them a call there tech support can help you find one.

 

Aren't the roller blocks like 1988 & up? Wouldn't any double chain listed anywhere for say a 1992 Camaro be appropriate? If so, just about every auto parts store has one.

 

Roller blocks are 1987 and up.

 

It seems like all the billet timing gears are for non-roller blocks..

 

I'm lost - are we looking for chains or gears? Or both?

Billet? They are hidden under a cover, and drowned in oil - who cares what it looks like, as long as it's strong enough to do the trick?

These are three of many double roller TC's that are available

 

Look at the applications of those double roller chains. It says Will not work with factory roller cam.
Factory roller cams have a thrust plate that takes up space. search Summit and you can find a AC Delco single roller for factory roller cams.
Is the OP working with a factory roller motor because his 85 was not a factory roller so we should know he is not working with a stock motor.

 

These don't have the roller block disclaimer:

I just used the Summit search for "timing chain" and then narrowed results for Chevy, V8, Double Roller, and 1991 engine (which should be roller).

I know I bought one from my local CarQuest several years ago for my 1990 TBI motor (which is a roller block) right off the shelf.

 

Both. And I agree.. they are hidden, but I have a billet cam and a two piece billet cover so might as well just buy the billet gears also. If you knew what kind of person I was you would understand that Im a nit-pick-f$#!, it sucks but I cant help it. As for the motor its a summit 383 roller block going in a 85 iroc.

 

Oh - I understand the nit pick - I myself am as **** as my wallet allows, and trust me, my wallet allows more **** with my car than anything else. I'll gladly (and have before) eat bologna sandwiches for every meal for a month if it means getting enough cash scraped up for the part that I want.

Kids are hungry? Nonsense, they ate once today at school!
DADDY NEEDS CAR PARTS DAMMIT!

 

Thats a funny story.. I just had a bologna sandwich today.

 

And oh yeah.. I just need to say... GO PACK GO!!

 

The EDL 7801 Edelbrock by Cloyes is for roller cam blocks, double roller.
