Don't feel so bad guys, I too was disappointed with my dyno numbers. I was shooting for 400rwhp and come up with only 339.5rwhp and an wopping 316.1 ft lbs.

I had 1 3/4 stepped to 1 7/8 long tubes (way to big for my little 306). I changed to 1 5/8 - 1 3/4 and could immediately tell the difference in torque (seat of the pants-o-meter).

But still...

I feel you guys' pain!

I have pondered the notion of switching over to a Holley manifold (I run a Victor 5.0 w/ a 1" spacer), but I haven't even seen what my current combo is fully capable of. I have a problem with switching stuff around too much, and not going to the track enough!

Best of luck to ya guys...
