Since you say you want to cruise the highway, you are just like the rest of us...you want it all too. That's Cool...but just realize there will be some sort of sacrifice to max the launch and maintain the highway cruise.

I have to admit, I'm a 3-Pedal Geezer too (like Dave Severson...I like the 5 & 6 speeds with the 4.10s or 4.11s). It has been years since I have run an automatic. Only after my knee gives out will I swap trannys. But thats a whole nuther post...

I also think highly of the Gear Vendors...but get ready to drop some $$$. They are great but pricey.

In my humble opinion, there are several things to consider before you can know which converter is the right one. RPM range of your torque curve & hp would be my first thought, then I would add in tire diameter & your rear ratio.

Once you determine you best ratio, you can get close on which stall converter to select. This isn't very hard to do if you know the formulas to calculate the transmission gears/tire diameter/rear end ratio to know where your rpms will be at specific speeds.

There are many websites where you can enter your data and determine your rpm/speed so you know where you will want to shift to max your energy before shifting. If you can't find one or if you just don't want to take the time to look, let me know and I will email you an Excel spreadsheet I created to calculate this for me when I was trying to determine which gear ratio I wanted to run with my current 6 speed. You can select various tire diameters, gear ratios, speeds, and transmissions to play around with the data so you know which will work the best for you.

Anyway, I'm always willing to help hot rodders so send me an email address if you want to take a look at it. You can always delete it if you don't think it helps.

Glad to see you moved into the real hot rods! Welcome to Americana!
