1927 Chevrolet Frame Fabrication, Engine, Transmission Placement, 1931 Chevy Coupe Build, Pinion Angle

We cut a few inches off the rear and moved the crossmember forward
So my friend Josh came to Oregon to help me for a week.  He is a welder and would make sure the frame was done correctly.

The rearend was from a Caddilac limo and had this triangulated four link design already built in so it worked great.

Making the sparks fly!

We set the engine in place and the cowl to make sure everything was going to fit.

Here the Ford Model A front crossmember is installed to lower the front end.  You can see that the frame is fully boxed now too.  Always make your body mounts before boxing the frame, I failed to do that on this car.

The motor mounts and the transmission crossmember are installed.  I bought Model A to Chevy 350 motor mounts and modified them to fit the wider frame of a 27' Chevy.  I got a 40' Ford axle off ebay, some 39' Ford spindles off ebay then the rest of the frontend parts from Speedway Motors.


We made some upper shock mounts for the rear.

This is basically the progress Josh and I made for the week.  The transmission angle is -3 degrees and the rear differential pinion angle is +3 degrees so when the suspension compresses under acceleration the drive shaft is at 0 degrees.
