  1. Mark A Jones Deltona Florida –

    This M22Z trans was built for my 1970 Chevelle SS 402 bb stock configuration which had a frame off restoration 7 yrs ago. Changed from auto to manual. This made the Chevelle much more enjoyable to drive, a huge performance enhancement, gets the cam in the rpm sweet spot. Conversion looks identical to stock since most parts are all stock bolt-ons. You can use a lower numerical gear to bring the highway rpm down and still have better than stock ratio performance. The sound of the M22Z is awesome, just like the old days. Jeff is a great guy to deal with, many years of experience. Awesome packed in a wooden shipping crate. Best money I have spent on my Stock restored true SS Chevelle. Thanks Jeff

    I bought a Muncie M22Z from Jeff and am very pleased with the unit. I had to wait a while but it was well worth it. The trans came professionally packaged in a crate safe and sound to my house. My Camaro now takes off like it has 4:11 gears in first but can cruise in fourth with the 3:08’s Excellent experience! Would highly recommend!!

  6. Brett Henson –

    Update. I’ve Got the M22Z installed behind a mild built 283 SBC. In a 57 Chevrolet With 3:36 gears. It drives and runs like a different car! Made a world difference! I Love it!! Thanks for your help Jeff. You are the man!!

    I put an M22Z behind a 469ci Pontiac engine in a 1966 GTO with 3.36s. Very happy so far! 12s on the BFGs. Shooting for its first 11s pass. I just put some Mickey cheaters on it. We’ll see how it holds up to the newly realized torque. Thanks Jeff!
