C4 converter

Post #1 by 64-5mustang » Thu Nov 30, 2017 10:36 pm

As I'm slowly building a 66 200 in a 64.5 mustang has a c4 auto 8 inch rear 3.50 gears I might go with a cam that might require a higher stall converter, at this point I don't have anything apart to find out exactly what I have. I'm going to stay with a cam with a lobe center of 112 looking at VI cam csc 264 112 it does claime to require a high stall converter, what will I need to look at to know exactly what I have when I get it apart? are there high stall converters available and where? Is this a thing that's needed? Thank you for your time.

Many transmission shops send the converters out for rebuild, and they can tell you who "that guy" is.
I sent my converter to the local pro and he was able to add about 200 rpms to my stock stall speed.
My car is still down to a shell so I can't give you results yet though...
HTH,

BTW, I'm going with the same cam as you, and 3:40 rearend gearing, great minds think alike :o)

All the C4's used behind a 200 six had a very tight (1650 RPM stall) torque convertor. If you want a higher stall like about 2200 RPM or more then it's going to have to be custom built. Good luck :nod:

I am still hunting for a project car to build but with my current low budget it's not looking so good. My Ex- Fleet of Sixes these are all long gone! :bang: 1954 Customline 223 3 speed with O/D, 1963 Fairlane project drag car with BB6, 1977 Maverick 250 with C4, 1994 F-150 a 300 with 5 speed.
