Would someone give me their coil location as shown here?
This is at the #2 cylinder (passenger front)

I'm told the LSA has different coil/valve cover mounting locations from the LS3.
Not sure I will have clearance for an aftermarket set of fuel rails with this coil location.

Any help is greatly appreciated.

Thanks,
Lonnie

Bad light and couldn't really get the tape threaded thru there. Maybe I can get a better pic in daylight...

It’s a half inch lower. If you want to remove that coil bracket and just mount coils to the covers then get lsa/ls9 covers and reuse the ls3 coils on the covers. So much cleaner

this is a pic from the right side. Lsa/ls9 covers used instead of the ls3 and bracket.

Thanks for the info.

I was unsure if my current location will clear an aftermarket set of LSA fuel rails, but I also hate to abandon the coil covers I already fitted to the engine... they currently mount to the coil bracket mounting studs.

Well if you don’t want to change the valve covers then you have to remove the brackets and mark a hole 1/2 inch in center directly above it and drill to relocation the bracket holding all the coils lower and not to interfere with the fuel rail. Either way you’re almost there at the valve covers so I would ditch them and put the ls9 covers on and call it a day.

Just saw the pic. It sucks but you still have the remove them to lower the brackets a half an inch to clear the rail. Has to be done all lsa swaps with ls3. That’s why most just use the ls9 covers. No bracket used.

I'm hoping I can still use the coil covers.
They were $180 plus about 4 hrs. of trimming to fit the vehicle.
Unfortunately they mount to studs holding the coil brackets on.

I never realized the LSA & LS9 valve covers are the same... you learn something new every day lol.
I have an LS9 engine here I can borrow the covers to test for fitment.

I have a feeling the lower coil mounting will put them directly into the heater box.
The one at the master cylinder is already relocated.

Things were going too smooth.

I'm betting on your skill set to make it work...

I swapped my LSA for an LSX, here is what I did for the coil placement. ICT plates, will also need ICT spacer kit using stock coil packs for the plates.

@kittyboy are those ICT's?

Yes, I fabricated two steel brackets and mounted them to inserts drilled into the valve covers. Then I drilled the ICT coil brackets and mounted them to the valve cover brackets. It works excellent! My valve covers appear to be about the same size as yours. Sounds like a pain, but in is an easy mod solution, super cheep too. The cost of the ICT brackets was about $30.00

As a follow-up to this, I ended up lowering the brackets 5/8".
With aftermarket fuel rails, the coil wire connectors were against the coils at a 1/2" measurement.

I tried the LS9 covers, but unfortunately, they move the coils almost 1" & my plug wire connections were against the heater box & the master cylinder. The LS9 valve covers also do not space the coils equally, which did not work with my coil covers.

In addition to all the bracket relocation, the covers required a bunch more cutting & fitting.... then of course repainting.
At this point I think 1/4 of the covers have been cut away.

Here is the final outcome.

Looks nice. That’s really shoehorned in there!!!

Yes, it is... You have to take the front tires off to change the spark plugs.

You had to one up changing plugs in the V....didn't you.

The Cadillac would be fun in comparison.

Also, 4th Gen Camaro/Firebird... especially the old LT1's with factory manifolds probably are the worst of any car I have worked on when it comes to plug changes.
