442 WITH OLDS 403 vs 2013 SS CAMARO - MARTIN US131
Here's a video of my last run at US 131 Motorpark Dragway after tweaking carb jetting and timing over the summer. The Olds 403 has a very broad torque curve and was able to take the SS in the quarter mile. The early #5 heads on the Olds do well for what they are but it is hard to deny the power that LS technology can make. The videographer missed the most important part of the race....The track times! Enjoy.
