Haven't been around much, so I thought I'd go back a while, and drop some pics of my 62 C-20, after the 402 swap. It's rude, crude, and cheap....Just like me!
Just FYI, It's a 70 402, with nothing more that an RV cam, a fresh kit, in the Q-Jet, and a set of Headman TightTube headers. The handshaker is the original SM420, and outback, is the big Dana, banjo-dropout style, rear end, with a 71 3.90 positrac pumpkin.
Between the headers, the torsion bar front end, and trailing arm rear, the 2 1/2" duals were something of a challenge. Just for tone, I ran inverted glasspacks, and 2 1/4'" tailpipes. For simplicity, I dumped them out right in front of the rear wheel wells.
