Hey guys, planning on the XE 224/230 cam, I also plan to pick up the GM Extreme Duty LT4 timing set due to wanting to keep my crank position sensor.

It is necessary correct? As far as I have been told it's not worth the risk to run a fresh stock LT1 set?

 

It'll be fine as long as you don't spin it really high, keep it around 6200 and you shouldn't have problems

 

You'll be fine with a stock timing set, but for $250 why not go with the LT4 set? I did, and it was definitely nice seeing the difference between that and the stock set. Much beefier gears. I recommend using the LT4 Extreme Duty but many have used stock ones with no problems.

If I where to run a different timing chain I'd go with a double roller conversion, won't cost much more and you'll get some more power and durability from it.

 

He's not going to be able to go with the double roller conversion and retain his crank positioning sensor for OBD-2, since his car is a 97. Also, I believe he would need an electric water pump.

Correct, which is why, since I want to keep my CPS, I need to buy the Extreme Duty set if I want something beefier.

I actually do want the electric water pump but I'm going to have to wait on that one a bit since I can't really afford to get the WP and the double roller at the moment The water pump removal/install process is quick & easy for me so I don't mind doing it later.

I guess it's better to be safe than sorry, so I'll probably get the Extreme Duty

Any other opinions still welcome.

 

eh, i use the stocker w/ no problems...

i spin mine to 6700 w/ the xe 230/236

i read that comp also made an LT1 timing set in a GMHTP a couple months ago...

 

double roller=$70, csi pump=$140 so theres not really much difference in price and you get the benefit of the e pump. Sorry I didn't bother to look at what year you had.

 

I had to make the decision of the LT4 chain or converting to the vented opti, E-water pump, and double roller.

I spent the extra money (my non-vented opti was almost new, though I DID sell it......) and went the cloyes double roller setup. No questions on strength there, and may have gained a couple HP in the process.

 

I actually moved from the Cloyes to a stock one. I was mainly having clearance issues and just didn't want to fool with it at the time. I'm pulling enough power to spin the crank hub on a NA engine and haven't had a problem yet

How did you have clearance issues? I did NOTHING special to install my Cloyes; I pulled the water pump drive and plugged the hole, but nothing else.

 

I had some clearance issues on mine.
I just used a high speed air disc sander and grounded about 40 thousands off the back of the timing cover.
I checked the clearance first without the gasket installed and made sure it clearanced it without any problems. And than when the gasket is installed there would be no problems for sure.

 

Well, mines a 95, so i'm not sure if anything is different. The first time I pulled the cover cause of some problems, i noticed it was contacting the timing cover. I left it alone and changed back over to the stocker when my GM pump locked up. That engine wasn't long for this world...lol
Wayyyyy too many problems
