that's what i was thinking. you think my hiccup with timing could cause that slow of a time?

Timing "could" be it all, but I doubt it's all of it. For sure a major suspect in a contributing factor.

Is your throttle going all the way open when you floor it?? That has got many people, smart people too.
Timing, get it right. READ THE PLUGS !!!! Plugs will tell you the initial AND total, and if it's right.
Compression test. Some have "thought" the engine was up to snuff, only to find a cylinder or two around 80 psi (not good!)
Take your time, and pay attention to detail. Don't let 7 of your friends each have a half hour alone under your hood to solve it :D :D
