You have lost so much power, and right on the launch. That says it must be the ignition some how. Ther would be enuogh fuel in the bowls to carry you almost to the 60 ft clocks. Bad coil? Trigger wire picking up signal from another wire, poor conection, hopefully you do NOT have ignition wired any where through stock wiring. Coil wire have a break or bad connection?

I am confused too! Is the motor in the car or out? Why did you not make a full pass? Was out put it back in. I put zippers on it so it’s easier 😂

Same as before 10.50's or same as before 9.70's? I thought that your G tech showed marked improvement. What changed since your street run the other day?

Look at the converter. Something is eating power.
I'd pull the engine and get it on the dyno to rule that out.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

136 mph? That's fast enough for a 9.70 pass. Something is wrong on the launch. The top end charge seems to be real strong. Carb, ignition, cam centerline?

It went 10.55 st 136 ? I just don’t get it . It comes out kinda flat and then really starts to come on. I went from a best 60ft of 1.28 to today a 1.75 ... I don’t know what to do at this point .. It looks like converter time to me Have it checked now before pulling all your hair out
