Which torque converter would be correct?

I think if you are interested in a good cruiser, you already made some mistakes both in the cam choice and the ignition changes. That's why the convertor doesn't feel like it's working right and I'd bet it's down on power from where you wanted it. Where are you in CT?

Edit - I see you're in Vernon. I grew up there and have a bunch of friends in town. I'm about 25 minutes from you. PM me if you want to get together and chat sometime.
