timing chains?
I am getting ready to install my ECS blower cam and i am down to getting a mellings oil pump and a timing chain. I am looking at the c5-R timing chain or a double timing chain. Since they are around the same price that is not a concern. Which is a better option? Also spoke to chris at ECS and he said the new mellings oil pumps are not having any clearence issues with the double chains. Any tips?

I did the D/roller chain with the stock cover it will work great, if you just do a little grinding on the inside of it at the key points...

Installed a double roller and had to grind the Melling oil pump (from ECS) for clearance.
Then had to grind and mill the timing cover to clear the oil pump (spacers installed.)
Installed the IW 8" balancer and then tried to turn the crank after getting it all together and it wouldn't budge. - had to buy an new oil pump
Balancer had damaged the oil pump cover.
Had to turn down the end of the balancer in the lathe.
Also honed out the inside of the stock balancer - used it as a guide to center up the oil pump.
It's been six months and running ok.
Recommend going the LS2 route if possible.

LS6 chain is no longer avaliable, has been replaced by LS2.
Only issue with LS2 is the chain has alot of slack due to the fact that robots build the LS2. LS3 tensioner cures that problem.
C5r Katech chain is the cream of the crop for single chains
