I've thought it might of of interest to document my TH400 build, hopefully sparking some discussion around of what is best. Like my rear end build, the transmission was originally one of those things "Black art" and best thought as being left to the pro's. I have had very good success with my 12 bolt bui...

I'm interested in doing a heavy duty overdrive. Will a 4L80E fit in the Tunnel of a 65-70 B Body? It's a very big transmission, and the tunnel seems pretty small.

I just changed the thermostat & gasket on my 67 Parisienne and it leaks from the thermostat housing when engine runs. I just tightened it to what I think is the safest I should. Any opinions for solutions?

The carburetor on my 65 Acadian Beaumont SD with a 230 6c has a hesitation and the last mechanic to look at it said it was hard to replace or repair. Any suggestions would be appreciated.

Need to replace drivers side engine mount. Engine is a small block. Does the power steering bracket go against the block? Or does it go on the engine mount? I would think on the engine mount As it is now power steering bracket touches the block first... and to me it looks wrong

I am just researching electric fan possibilities on a big block. My 396 runs nice and cool (185) on the highway but slowing down in traffic, the temp gauge will climb up to 200.
