     '53 to ’66 Buick Nailhead

    '53-'56 nailhead kit         '57-'63 nailhead kit         '64-'66 nailhead kit

Due to the many changes in transmissions all thru the ‘50’s and ‘60’s, its no wonder that no one has attempted to tackle the difficult task of designing engine to transmission adapter kits for these motors before. Have no misconceptions about how much time and effort went into the development of these kits. Every time the transmission changed, the flywheel changed, sometimes the crankshaft changed, and sometimes the starter changed. One of the many difficulties was trying to achieve universality so that I wouldn’t have to stock 13 different kits to cover 13 years.  Success! 3 kits now cover all these years. 1 kit covers ’53 thru ‘56, another fits the ’57 thru ‘63 while the third fits the '64 thru '66. These kits allow you to use any Chev transmission built for a V8 from 1955 to 1997, stick (will work but not recommended for racing) or automatic. You may have to do a slight block modification on the '57 thru '60 blocks.  You have to drill an extra starter hole, and cut a small ear off of the block.  Then you will be running a '64 to '66 starter.  Try your existing starter.  If it doesn't work with the supplied flywheel, then try this modification.

One of the criteria that I wanted to achieve with this kit was NO modifications to either the block or the transmission case or torque converter. The slight modification it takes to achieve my goal is minimal. For the most part it even allows you to retain your original starter. The flywheels are custom made (except the ’64 to ’66) and balanced. All parts are CNC machined and ground. All parts are American made.
