331,opinions and info

rbatson - I'm surprised that KC would say that. I guess the way I look at it is that you gain power by keeping excessive oil away from the crank, but still allow enough to lubricate and cool. Additionally, with a high volume oil pump, it should be able to sufficently supply oil to the entire motor - even with a windage tray.

My engine builder suggested a windage tray based on his 18+ years of building high performance speed boat and race car motors. I'm going down to see him this weekend, I'll see what else I can learn about windage trays.

I'm also curious about where my new 331 will make its power (both HP & TQ). I'll be paying a visit to the same dyno that I used with my old 302 mill, so it should be interesting.

One thing that I learned from my last dyno session was that my HP dropped off much sooner than I thought. Peak HP of 289 RWHP came at 5300 and peak TQ of 312 RWTQ came at 4500. 90% of peak HP came from 4400 to 6000 and 90% of peak of TQ came from 3600 to 5300.

I'll let you know how it comes out.
