What are your opinions on timing chains? Should a double roller timing chain be used and how much of a difference does it make on an engine that isn't highly modified?
Hands down Cloyes. Timing chain quality isn't just something you determine by how much spring pressure you have. If you want an engine to last, put a good chain in it.
Make sure you remove the spacer behind the cam gear.. A Cloyes cam gear and maybe others come's with a spacer machined right onto the back of the gear,at least the one in my truck did.... so if the the original spacer is not removed, it will push your cam back into your block about 3/16th inch...Causes a whole list of problems.
My 390FE is pretty much all Edelbrock components. The timing chain set is no exception. Part #7808. Good quality product, but only recommended for Edelbrock or stock cams.
OBTW...they are made by Cloyes.

Summit=junk. I ordered a cloyes true roller from them a while back and they goofed and sent a summit pile of junk instead. Every link was stamped taiwan and looked like junk. Ended up returning it and getting the cloyes for the price of the summit chain ($70 savings). Has anybody ever bought anything "summit brand" and had it be quality? They're like barely-scrape-by parts that you're forced to run only when you're completely broke and have to have something running.
Cloyes Tru-Roller. Nothing else is even close. When I ran Speed-Pro I could have the Speed-Pro timing sets for free - - and I still went out and paid for the Cloyes stuff. I like them that much.
