Finally got a decent camera (new smart phone!!) to take a video of my '70 Duster...

360 LA bored .060" over, Magnum heads, KB flat tops (10.5:1 compression)
Lunati Voodoo hydraulic 256/262
Hedman "Tight Tubes" shorty headers
2.5" Pypes exhaust all the way to the back
X-pipe crossover
Classic Chambered "Powerstick" mufflers 26" long

This is a cold-start video on a 85* summer day

And just for comparison here's one of my old 318, had the same cam but with stock worn-out bottom end.
