Which posts advocate PEAK hp over average torque?

My answer to the actual questions:
1. Build it as big as possible (cid)
2. Build as much compression as your fuel will allow.
3. Match the cylinder head to the airflow requirements for your cid @ 3-6K rpm.
4. Run a big solid roller.
of course, my idea of "best" performance may differ from yours... what unit of measure are you using to quantify "best"?
The parameters for my build were:
1. Small Block
2. Pump gas
3. 3-6K rpm
4. single 4-barrel, naturally aspirated
5. street/road course
My build specs (eng #1):
434 cid
9.6:1 compression
AFR 210 Head
Solid Roller 264/272 @.050, .650 lift, 106 LS
750 Stealth Racing Carb on a Victor jr w/1" spacer

Of the 4 engines I've had in my Cobras, I've always built them for max power in the 3-6000 rpm range... because I drove them on the street as well as the track. An frankly, the power we made in that rpm range was probably more than my average skills could use anyway.
