L92 headed 409" engine with that new GMPP dual plane intake.
It made 522hp at only 5700 RPM and 516 ft lbs at 4200 RPM.

As a side note, That engine made 600hp & 580tq at the D&A shop with that tiny cam.
The crappy gas that was used at EM required every entry to dial back the timing and tune considerably.
Give Don a call, he is a nice guy. Here is a link to D&A Machine Shop page:

No, from what I have read, the specially formulated 91 octane "california blend" gas provided by Rockett for the engine masters competition was absolute junk.
Every entry suffered because of this. I also read that 10 engines were lost to detonation from this junk.
