I added a vent in the top of the bellhousing

I added a new flange in the front of the bellhousing to accept the side mounts I had built into the R 154, so now 8 mounting bolts can be used, I also raised the two lower mount area's so the engine can set lower

I raised the floor of the transmission side of the bellhousing using individual mounting bosses to save a little wieght and I liked the look

I took some 5/16 aluminum rod and bent them at the right angle and welded them on the outside of the bellhousing aligned next the the mounting bolts

Then I molded in the rods with body filler and filed it down to shape, notice how long the lower mounting bolt housings are, the inner ring around the flywheel was the thinnest part of the bellhousing, in an effort to provide more strength, I used a much longer lower mounting bolt so that it ancored beyond the thinnest part of the housing, that way you can choose to use just 4 engine/bellhousing mounting bolts and still have the required strength to use a rear transmission mount

It requires hours of filling and filing and sanding and do it all over again and agian until you get the right size and look

I made the gussets much taller this time hoping to gain added cooling from air circulation

Now this is and excellent ,low cost, strong entry level set up so anybody can afford to build a RWd 4G63 narrow block

This bolt pattern fits both the first and second gen 4G63's
