Just curious what others have seen as far as total ignition advance on LS3 headed stroker (408, 415, 416, 427 etc) engines.
I am current at 22-20 final on a 416 I am working on, it seems happy and the spark plugs look good. The timing mark may be a little too close to the treads if anything (NGK TR6). Thinking about trying a 7 heat range, or backing off a couple degrees.
Forums are full of timing info for stock displacement LS3 engines. Thought I would see if I could get some info on higher displacement LS3 combos. I thought 20 was a little low, but it runs great.
If you don't care to share, please include the plugs heat range, and fuel.
The engine I am tuning is on 93 pump gas, with TR6, and about 11.7:1 Compression.
Thanks everyone!
