Billet LT1 Timing Cover - Clears Double Row Timing Chain

[S10Wildside]

The production 96-97 LT1 timing cover has several issues...
- it is no longer in production
- it does not clear a double row timing chain

There have been requests for a solution to these problems and the solution is almost ready for production. After a little test fitting and actual run time on the test engine, these covers will be ready for purchase. Price will be announced after all testing is completed; before the end of this year.

This is great news for anyone interested in EFI Connection's 24x system where a double row timing chain is needed for an LT1. The 24x crank reluctor for double row chain will fit in this timing cover (where the production timing cover has crank seal area clearance issues).

Looks nice...... looks expensive, but if you have to have a double roller chain with your setup, this is the only way to go and use the 24X system!!!

Keep up the good work Mike!!!

"Expensive" is relative. :) Consider that this is the only reasonable approach to making a new timing cover for the LT1...being that it's going to be a small production sort of thing.

Some have told me that cast aluminum would be the cheapest. Yes, but not before thousands of $$ in tooling, $35 or so in each casting, and then the price of fixtures for the CNC, design time for the CAD work, and actual machining. And this is going to be a low production item anyway, so that means these costs have to be absorbed from 100s of covers, not 1,000s of covers.

With the same reasoning as the cast approach being cheapest, you could argue that injection mold is even cheaper...but the costs of making the first cover would easily exceed the cost of making the first cast aluminum cover.

So...here we are with a billet timing cover. The cheapest approach by far. Even with the cover beginning as a 20 lb piece of billet. :shock: The final piece is slightly lighter than the GM cover.
