Chevy 216, 235, 261 to V8 Style Transmission 200-4R, 700R4, 4L60E, TH400, TH350. Number CH301. (We will need to know year, make model and what motor and what transmission your going to)

While performing this installation, please remember a few simple rules.

1. Install all bolts before tightening in a particular sequence
2. Use Loctite and torque bolts where applicable. Never force anything
3. Lubricate both threads
4. Trial fit everything to make sure it will fit. See rule #2.

Installation Instructions

1. With your transmission removed, clean the back of the block where the adapter will contact it.
Make sure both alignment dowels are in place. If you have three alignment dowels remove the
one on top. Bolt the adapter plate to the block with the 5 flathead screws. Due to the
differences in engines over the years, it may be necessary to fit the plate to the block. They
weren’t all made exactly the same. You may need to grind the block slightly where the weld on
the starter bracket contacts the block. Also check where the starter bracket touches the oil pan.
Some pans hit the bracket. If this is the case, grind either the bracket or the pan rail. This is a
tight fit. This is so there will be a rock solid starter mount. Now install the provided flywheel
using the 6 flywheel bolts provided. It only goes on one way and is a tight fit. This flywheel has
an O degree mark on it for timing. You should now be able to bolt any Chev automatic
transmission to the back of this motor. This kit is for use on motors with a 6-bolt crank only.
GMC takes a different kit. This kit is designed to use a stagger bolt Chev starter from most V8s
from the late 60s to the early 80s. Just as long as it is for a 168 tooth flywheel. Chev only had 2
different flywheel patterns for many years. A 153 and a 168.
2. Important! Check to make sure that the pilot on the torque converter you plan to use will fit into the
crankshaft. Some of the early 216/235/261 engines had an inside crankshaft diameter of 1.686. The
standard torque converter pilot on a GM converter is 1.702. You will have to remove some material on
the converter pilot to get it to fit if this is the case.
3. We will not warranty flexplates that are bent due to installer error! Make sure the converter is trial
fitted before bolting trans to adapter!
