I am going to change the timing gears and chain on the truck soon.
What brand is best.....no HiPo stuff. Just a good quality OEM type.

All stock.
 
I like Cloyes HD timing sets for basic use. You should be able to get a double roller set for 25.00 or less. I know Summit has them for cheap.
 
Don't go cheap on a timing set. All it takes is a broken chain or gears to ruin your day. I like cloyes roller chains the best. Trying to save a buck usually cost you many more than you thought you saved.

x2. considering all the problems that can happen after the timing set fails, it's way cheaper in the long run to get the good stuff up front. i have dual chains on mine. too bad gear-only sets cost so much more. that's really the best way to go.

Maybe a quiet set may help there , I know the whine sounds cool , almost as cool as a guy in a musclecar backing up at a drive in with a spool :thumb:
 
I have heard of issues with the knock sensor when using a gear drive set.

interesting. i hadn't heard that. they do make quieter sets but they cost more. something seems strange about that, though. why would it be causing so much vibration that the knock sensor detected it? sounds like improper install or something.
 
Has anyone ran a gear drive on a truck with a knock sensor?

I put one in a GTO when I was in high school. The noise was cool for a while, but I got tired of it.
 
I can't remember if I need to drop the oil pan to change the timing chain/gears?
Last time I did it to a chevy SB was over 2 years ago.

The knock sensor picks up the resonance and there for changes timing.

You can sneak the cover off if you loosen the first several pan bolts on each side. Once the cover is off you'll see where it hangs up and you can trim the cover a bit to make any future removal much easier and also easier to reinstall the cover this time.
 
This is a great time for me to fix the leak around the timing seal also.
Do the new timing sets come with the gaskets for the timing cover, water pump and all that crap?

Yes they do.
 
Summit says no, will Vato Zone come with it?

I only want to make one purchase here, so the wife doesn't think I am trying to nickle and dime her to death.:haha:
