Lt1 question!! Belt Drive help!
Lighter, more reliable,stronger, and the ability to set they cam timing on the dyno.
Jesel makes one but you have to eliminate the opti spark, I was hoping to find a belt drive system that works with opti.

As far as reliablilty goes, get a double roller...it won't break and you will have to swap to an electric water pump, there's your reduced rotational mass right there.
You could also get an adjustable cam gear and do the same thing with a chain, but why?
Get your cam ground with the advance/retard you want, and the timing is computer controlled. You tune it on the dyno, not change the cam gear. Sounds like you want to use nostalgic methods on a modern car, which would be unnecessary.

I think something like a Hex-adjust is about as close as you are going to get. I know it is still a chain but this easily fits and does not interfere with the opti.
Just as you play with cam timing remember to offset the ignition timng to get it back to where you had it.

Verdad Gallardo Have you heard many stories of LT1 timing chains breaking? Reduced rotational mass is always a plus, but the amount to be gained by what you want doesn't seem worth the money.

Money is not a question.
I might end up going with double roller, but I like the guarantee of timing belt working flawlessly @ 8,000RPM+.
Dry timing belt is the only way I know off that allows easy access to cam timing. Cam manufactures grind advance/retard into the cam that would work in certain RPM band on average setup. Max effort setup needs cam timing dialed in.
Thanks for all the input, but I really didn't ask why should or shouldn't go with belt drive - I just want to know who makes one.
The car is apart because of the snapped chain.

Remember, the LT-1, the entire front of block is a black metal cover, is not LT-1 but a regular 5.7ci. Facebook, messenger. Be happy to help you through it.

Remember, behind alternator, water pump, ac pump. While you have it all taken apart, not a bad idea to replace Omni spark. Since you are going to have everything out of the way. Let me know how it goes for you.... James.....
All you have to do is buy a SBC timing cover gasket and overlay it on a Lt1 timing gasket. Take that to a machine shop and have them cut out the delta from the same thickness and the Jessel timing cover. Then weld the piece to the Jessel cover.
super easy work
i did this years before I made my first turbo kit
