I'm curious: how much spark lead do these RB blower motors use? I've heard numbers as low as 15 degrees for LS. Yellow Bullet probably has some traffic on this.
id imagine every motor will behave differently. I had a 383 mopar on a dyno N/A and it loved timing. it kept making power at 41* I stopped adding timing and even backed it off a few, lost a few HP but it is street car. Back down at 20* the car was a total dog. Funny, I really thought 41* was just stupid high, but it loved it.
