I’m building four new Offset Distributors for the 8.2” SBF and discovered the SS V-Band Clamps I had planned to use wouldn’t fit correctly. As a result, I decided to machine my own clamps from billet aluminum. Stay tuned!

I had a fellow member on the BOSS 302 Registry ask me if it were possible to do a single plane manifold for the BOSS 302. I told him when I got a little time, I would see what I could come up with. The results came out pretty good. I placed the carburetor in the same location as the original OEM BOSS manifold. This will allow with the shaker scoop to be retained if your car was equipped. As with my other BOSS manifolds, it has the 3V port configuration. If interested, they will be $2250.

The previous owner of the shop left behind some homemade shelving units. I repurposed them to make four benches and had one section left over. I used it today to build a deburring bench for manifolds.

It was a busy day today in the shop as I’m finally back on machining manifolds. These are the first run for these manifolds requiring fixture development and manufacturing prior to beginning machining. First up is the BOSS 302 2X4 Tunnel Wedge R and the 302W 2X4 Tunnel Wedge. Tomorrow I will machine the next four 351W Tunnel Wedge manifolds.
