360 Magnum vs 340 mild street build - my experience

Well, ET does mean something if the car doesn't spin. Sometimes changes can add bottom end torque and move the car in the first 150 ft quicker. In the 1/8 mile I gained 2 mph. The side by side comparison to the cast heads was done with 2.94's. I had to go back and watch the video of result to get the results LOL

^^^ By the way, the car gained about 2 mph the last time out when I added timing. Soon after a couple other things are wrapped up, I'll be getting back to this car. It's been to long.... ha! Because of more compression and a better cam, I'm confident the 360 in our '80 truck is making more power and the Duster would go faster if we swapped.
