Holley Strip Dominator vs. Edelbrock Victor 340

Interesting ... My 408 has a 246/250 on a 108 and my heads flow 293 as well .
Peak power was at 6200 using a stock Victor W2. I thought it should have turned to 6800-7000 .
HP peaked at 493 but I realized after the dyno session I had 2 qts too much oil .
What was your hp ?
