Edelbrock LD4B

Thanks for the info. As I'm not a mechanic the conversation is a little over my head. I've had my engine on a dyno and it confirmed what I already knew. Torque was all in the low end and hp dropped off quickly after 4000 rpm.View attachment 1715125465

What car was this? 2900 lbs? Why did they turn the inertia off? Do you have a dyno graph? What's the combination being tested
here?
