Thanks, guys.
I was leaning more toward fuel, as the fact is the RPM is not the limitation, it is the wide open throttle that causes it. If I just rev it up slowly, I can reach 6,000+ rpm...but floored, it does stumble horribly. At first I thought I had a rev limiting rotor which was too low, but like I said, I can rev it higher, just not "mashed"
Rather frustrating, as it is still making gobs of power at 5,300, and in fact I believe the peak HP is higher still...I really don't know how fast my car can be.
I will definitely check the gap...that was one of the first things I did when I got it home (changed plugs).
Also will look into the distrubutor.
Unfortunately, I won't be back home where the car is until Sunday. I'm on TDY in Vegas, holed up in my hotel room watching "Top Gear" episode after episode. Great fun! (Not much of a gambler...though I did hit the Roulette table for a while earlier this week. Got spanked.)
