im looking for a double roller timing chain for my 91 rs 305 tbi while its all apart. i know cloyes is prob the best and thats what i was considering but im having a hard time finding the correct one. Also if anyone has alternitive ones for my application , fee free to post them..

thanks

 

you'll need one for a roller cam. i use comp cams 2136

 

PAW sells a PAW-brand double roller timing chain for roller cam equipped SBC's.
If you're on a budget, that may be something you'd want to check out.
I don't have my catalogue handy, but if you want a part # and price, just ask and I'll get off my fat butt.
PAW also lists a bunch of roller cam timing chains, unlike Summit, who aparently has forgotten that roller SBC's need timing chains, too.

 

I'd look into Cloyes also. I use Comp Cams though.

 

so all these either comcams or cloyes fit under the stock timing chain cover right??

 

Yup. They should sit under the stock cover no problem.

 

yes they fit under the stock cover.

 

great thanks guys

 

They'll clear the stock cover but some double roller timing chains will rub on the block on the top oil plug casting near the cam. I had this problem on my Summit double roller timing chain...no biggie, just grind the block casting with a dremel just enough to clear. Be careful with the shaving getting in the motor. Just be sure to check it or the chain will bind up and fail early.
