PostSubject: Bailey LTCC coil on plug conversion.   Tue Sep 23, 2014 1:25 pm


Earlier this summer the original Stock Optispark failed in the SS Wagon heading home from Bill's mod day. So I decided I wanted something more reliable and maybe a bit better.

After some consideration I went with the Bailey LTCC conversion. The only negative being you keep the Optispark but you only use the Optical portion and you are bypassing the cap and rotor which is what failed on me. I also didn't want to tackle the replacement of the stock computer timing gear and wiring harness changes that come with the 24X conversion. I may still consider this in the future maybe for another project yet to be named but the LTCC is a very nice product and so far I am happy with it.

The original plan was to have this work completed before Wagonfest NY but as these things go I ordered my LTCC box in between batches and it was delayed over a month.

In the short term I replaced the original Optispark with a NOS one along with a new ignition module and Coil I had in my hoard. I didn't want the car down while I waited for all the parts to come in for the LTCC conversion.

With help from JaySS (Thank you Jason!) we finished the LTCC install this past weekend. This was after the module arrived and we had time to complete the work. The LS coils and bracket were installed before wagonfest NY.

Since the conversion the car starts faster (Shorter crank time) and it runs much smoother especially at highway speeds. Throttle response has also been improved. I am quite impressed with this conversion so far.

The only problem encountered so far was the #1 spark plug wire. The car has first generation Tri-Y headers and they are difficult to work with. In it's original configuration the wire was too close to the header. The plug boot ended up touching the header once it warmed up and of course it melted. Luckily we had some wire left and were able to make a new wire with a different route.

The shopping list.
1. LTCC module. Made and developed by Bailey engineering. http://www.bailey-eng.com/
   (I would suggest emailing them to see if they are in stock. Bob is very quick to respond to questions and he also certified this configuration for me.)
2. COILS The recommended coils are what I went with. I ordered them new from ebay. GM Part number 12573190.
   The auction I purchased them through is still running.   http://r.ebay.com/4mLnFG
3. Coil brackets and mounting bolts. There are several options.
   I went with EFI connection. http://www.eficonnection.com/eficonnection/ItemDetails.aspx?ItemId=1340
4. 2 Factory LS Coil wire harnesses. ACDelco 357A GM Ignition Coil Wire. GM Part number 12579355. They are the same for both left and right.
   Purchased through Amazon
5. Plug Wires. I went with Taylor 409 wires.
   We started with this set and had to cut them apart to fit. http://www.summitracing.com/parts/tay-79226/overview/year/1996/make/chevrolet/model/camaro

And now for some pictures!



The black box in the RAISS is the LTCC box. We placed the box inside the air intake so it was away from heat and vibration.





In the following photo you can see where the ignition module and coil were against the aluminum head. Now they are gone and only the wiring harness grounds are left.

Doug, I noticed that the other night and wasn't sure if you had done that before or after Billy's house. That's pretty damned cool and just another interesting mod done to that car...nice!

This is probably my favorite mod to the LT1 cars. Not because it works better, but because it looks more modern and heavily badass.

Nice work man, looks good!

Thanks gents.

So far I feel that it has been a worthwhile project. The car starts faster and it runs smoother.

It also got rid of most of the highway chuggle that these cars all seem to have.

I will report more as the miles stack up. I am just over 150 miles on this conversion so far.

Now I have to change out the water pump that has decided to start leaking out it's weep hole.
