Hi all, I'm new to the forum.
This is my first LS build and to be perfectly honest, I love these motors now that I've had a chance to tear into the LQ9 6.0. Building this for my 68 Camaro.
I've added a Texas Speed cam, springs and rebuilt the trunions. Also added a Holley Low-Ram intake so far.
My questions:
Coil selection. I have the old coils from the Escalade it came from but not sure is they will have the output I need for the new build. What style and type do you guys recommend.
What throttle cable setup should I use for the conversion being my old linkage is rod design?
How about my stock injectors... Will they handle the demands of 500 HP?
I'm sure I'll have more questions but that's
it for now.
Thanks guys!

1 I've seen stock coils used on 1000 hp builds.
2. I can't really tell you because I'm using stock cable set up on my GTO and my Corvette was DBW.
3. If you're going to 500 rwhp make sure to upgrade the fuel pump to a walboro 255 at a minimum and 42lbs injectors again at minimum. I was pushing 538rwhp with this set up and a 150 wet nitrous shot. Never had issues with fuel delivery or injectors not being able to handle the fuel needs.
Stock coils have been very capable and nearly all of the aftermarket coils failed to deliver equal performance.
IGN-1A coils can provide a small gain on a NA engine. I seem to recall reading ~8 to 10hp on a 500hp engine and more in boosted applications. There are also some tuning changes needed to take full advantage of the better coils from what I've read. A member "PanteraEFI" who was a sponsor made several posts about them.

He now goes by the coil name, IGN-1A. I bet he might be dropping in if he's watching the forums...
If you're on a budget the Gen4 truck 50lb/hr flex fuel injectors (12613412) are plentiful and only around $100 a set. The Gen4 injector data needs to be converted to Gen3 to use with your Gen3 LQ9. The data is in the "Injector Data Sticky" here on the forum. I run these same injectors in my LQ9 truck with a Walbro 255lph and a 100hp wet shot.
On a NA engine, IGN-1A coils can yield a minor increase. On a 500hp engine, I seem to recall reading 8 to 10hp, with more in boosted situations. According to what I've read, certain tuning tweaks are also required to fully use the improved coils. A sponsoring member, "PanteraEFI," wrote multiple postings about them.real estate istanbul
