A truly complete conversion combining the Keisler PerfectFit^TM transmission  with all of the correct matched parts that have been carefully selected and tested by Keisler for guaranteed quality and performance. 

Drivetrain component selection and installation instruction and support is critical to get the job done right. Rest assured, buying from Keisler - the leader in manual transmission systems - is the first step in the best driving improvement you will make to your early Chevy II or Nova.

1.  TRANSMISSION - NEW TREMEC TKO-600 (600 HP/600 FT-LB), customized by Keisler to perfectly fit your 1962-1967 Chevy II / Nova. A number of custom features are included (with no hidden charges) that you won't find anywhere else, including:

• Shifter location custom designed for your 1962-1967 Chevy II / Nova.
• Keisler's modifications minimize the alteration of the factory 4-speed tunnel.
• Custom short-throw internal shifter mechanism designed to provide better-than-stock shifting.
• Muncie / Borg-Warner GM bolt pattern and input shaft configuration for direct bolt-in installation.
• Gear Ratios: 2.87 1st, 1.89 2nd, 1.28 3rd, 1.00 4th, .82 5th; 2.56 reverse.

Rich Bryant - '65 Nova SS

Just wanted to send a quick note and say thank you!
I purchased a TKO 600 Kit from you and installed it in my 65 Chevy Nova SS
I got the Kit with the offset Shifter I put the Hurst Shifter lever and the 4speed knob on it and with the 4speed console you can not tell it is has a 5 speed in it. People ask all the time is it a 4speed and I just smile and say No it a 5 speed and I got it from Keisler Engineering!!!!
Boy what a difference it made in the way the car Drives and Shifts, I have a 410 Gear in the rear and it dropped the RPM down to 2100 At 70 MPH from 3300 before at only 55 to 60 mph.
I would say the hardest part of putting it in was dialing in the bell housing.

Thank you for a Great Product!!!!!
