In one of my 5.0 tuner books they picked up 8rwhp on a stock engine with an ignition system and increasing plug gap to .060

They picked up like 10rwhp with an aftermarket ignition and a plug gap of .060 on a modified motor.

Both compared to the stock ignition. I wouldnt doubt if they messed with the timing to achieve those numbers

I have my plug gap set at .060 and I shift @ 6000rpms without any issues.

8 RWHP gain on a stock motor with only an additional .006" gap?

That sounds like F&F talk to me. Maybe more of the gain was attributable to the aftermarket ignition system? Of course, I thought the stocker was fine for minor bolt-ons.
