Looking for help fixing engine hesitation. I'm lost.

Do you know what the advertised stall is on the converter? I'm assuming the converter came with the trans.

another thing you can do is to put real gas in it instead of the ethanol version

The torque converter was an 1800 stall. I was going to go with a 2400 but decided to go with an 1800 because I thought that would make it more "streetable" It sounds like I should of went with the 2400. Also all I run in the car is premium 91 octane that says it contains no ethanol. None of that garbage in this car

It must be nice being able to have a choice on buying gas with ethanol in it or not. Everything here has ethanol in it.

1800 stall sounds kinda tight to me.

I agree the 1800 stall seems too tight, but usually when you have a converter that is too tight the RPMs will drop quite a bit between Park and being in gear. It could be that the converter is a little looser than listed.
What rear gears are you running?

 

[WisconsinCutlass]

3.73 posi rear gears in a 7.5"

Sounds like a problem in the accelerator pump circuit. order a acc. pump cam kit and try different color cams and different positions till shes feels crisp off idle.

So I'm very confused again. Last friday I couldn't get the jets for the carb so I put it back together with the #69 jets and #29 accel pump nozel. I bought a vacuum gauge and tuned the idle to the best vacuum I could get which was bouncing between 8-10. I drove the car about 200 miles since last weekend. I got my jets in the mail yesterday and put them in this morning. I was going to replace the fuel filter and put new plugs in and was very surprised when I pulled the plugs. They looked white almost as if it was running good or a little on the lean side. The picture of the plug is the same exact plug I had pulled and took a picture of earlier in this thread. I havent ran the car with the smaller jets yet. Should I try it and see what happens? I also didn't know that spark plugs were self cleaning. I was expecting to see black sooty plugs like last time. Where should I go from here? I'm thinking I should get a accel pump cam kit and try tunning that.
