Timing setup?

My motor has some mods, its a 355 with bored intake, and ported heads with bigger valves, LS7 lifters, and a 600" solid roller cam. I don't want a double roller, so I figured this would be the next best thing. I just don't want any surprises when I start to button this timing set up.

It is good insurance but Ive never heard of a stock chain or sprockets failing no matter what rpm. On my 396 build I will be using a HD timing set up but I plan to spray the **** out of it. Untill then everyone I spoke to basically said the same thing HD is good insurance but nobody has heard of a stock set up breaking either.

ive got a buddy of mine that his let go last weekend. now dont quote me that the chain failed, i want to go inspect it when he tears it down. now granted, he was revving to the max and spraying the **** out of a h/c impala. for some odd reason, i have a feeling it was something he did, not an actual part failure. but in saying that, i plan on running a double roller with mine for the added peace of mind. i have only heard of a handful of stock setups failing, but the people who state they break never follow up with an explanation of why take it how you want...

I am running the LT4 Extreme set and it is a really nice piece, if you look at the stock LT1 versus the upgraded LT4 there is really no comparison. Plus, like others have said, it retains the factory water pump set up eliminating the added expenditure of an electric water pump. If you add everything up, the LT4 set is actually cheaper than a cloyes double roller with EWP, yet still more expensive then stock replacement but I thought it was worth a little extra money for the piece of miind in a cammed LT1. The factory piece on a bone stock motor with 44,000 miles on it had already started to wear rather substantially. I haven't heard of an actual failure except the last post but if you need confirmation of a sloppy timing set on a low mileage motor I can vouch for that. Added spring pressures are going to speed the break down of the factory piece by quite a bit I would imagine.
