Big timing chain problem So I just had my motor rebuilt. Put in a new cam new pushrods lifters and springs. I was driving home last night and my timing chain snapped. WTF! Where can I get a new timing chain set and timing chain cover? Is there a stronger chain that I can put into the car without modding the motor? The one that snapped was a stock replacement from cloyes.

I'm sure someone on here has a Timing cover for sale my guess is the cam you put in has a snout for a Opti II set up so heres probably the best bang for the buck http://summitracing.com/parts/LUN-93094/?image=large better and cheaper then the GM performance one I'm sure if you search around you may find that one for cheaper but no promises
You need to find out if you did any damage to your valves and pistons. If there is damage it can burn your valves and pistons up costing you far more. The LT1 is an interference engine.
You should do a thorough investigation as to why your chain broke.

Yup, there very well may be other damage.

Agreed with posters above, thoroughly check everything. You don't want to put you damaged motor back together for the second time, only to have to tear it down and fix it for a third time...
It wouldn't hurt to get a Cloyes double roller. But you will have to delete your relctor ring and tune out the cps code. You also have to run an EWP to use the double roller. Not to forget you have to clearance the inside of your new timing cover a little. Since you need a new one, it would be best to get a '95 cover that does not have the hole for the CPS sensor.

And as previously stated in this thread make sure that you find out what caused the chain to snap and make sure the engine isn't damaged.
It is for clarity sake. There is both a LT4 and a LT4 ED. The regular LT4 chain's links are about the size of a bicycle chain...
The remedy was the sooper dooper oversized crank gear which then yielded about .020 clearance between the cam and crank gear...
