Thunder bolt IV timing question
Anybody know what rpm the TBIV ignition reaches full advance? Also how much advance can you squeeze out of these units

Absolutely, the SC motors had different curves than the NA motors so you need to do some research on where the module came from.

It's a v8-24 unit from a 260hp 5.7L. I upgraded to vortech iron heads, performer rpm intake, 9.8:1 compression, the lt4 hot cam with roller rockers and a 650 demon carb, I was wondering how much timing this setup will want.

Start at 32 degrees total advance and you can make small adjustments up from there. I doubt you will be able to run more than 36 degrees, and too much advance will cause detonation

With 9.8 compression you dont want too much advance. It also depends on if you want to run premium fuel all the time or not.
