If it does let that 400 spin 3300. The Warp will take it no problem. The 400 has a max torque at 3200 stock.

My point in saying what I did was that if advancing the timing had the effect I thought it might, I didn't want him to over-rev the prop.
The goal here will be to get the engine happy at 28-30 degrees total advance and then pitch the prop to hold it to around 3,200 rpm.

Olf I agree. Gotta fix one before the other. If he gets it right it will run damn good.
