If you recall, I installed a 347 in my Tiger and wanted to stay with a 4100. Long story short, Ed built me a 4100 for the 347. I was not happy with it (no knock on Ed) then tried a Holley 600 and 700 CFM Double Pumper. They did OK but still was not happy.

Here is where I am today -

Running the brand new Holley Ultra HP 650 carb.

I am in the middle of tuning it with a wide band O2 sensor with gauge.

Neck deep into:
Emulsion Bleeds
Idle Feed Restrictions
Power Valve Channel Restrictions
Idle Air Bleeds
High Speed Air Bleeds
Power Valves
Main Jets
Squirters
Accelerator Pumps

It is coming along nicely as I am shooting for a tune that has the engine cruising at an AFR of 15, WOT 12.5-13 and a partal throttle under all loads of 13-14.

Here is a bad video of when I got the WBO2 sensor http://youtu.be/86erf8z_cKY

That is one sweet ride!!
Ya, it took a fair about effort on the dyno to get my 4100 to perform.
It's great for the street. The odd time I get to go to the track I use a Shelby 715cfm. It's good for another 1/2 second.

The fastest run last year with a E-bay 700 CFM I rebuilt.

R/T - .353
60' - 2.070
330 - 5.267
1/8 - 7.957
MPH - 91.27
1000 - 10.270
1/4 - 12.211
MPH - 116.09

The Ultra HP 650 was day and night better out of the box and was running fat as hell. Can't wait to get it tuned and to the track........11s for sure.
