Slow 1/8 with 74 440 dart

yes it revs to 6k very smoothly now. i was so impressed how much of a difference that made. i think based off of my plug readings though i've got a bit of tuning to do with my carb. i've got pretty mild jets and a 3.5hg power valve to accommodate my 7 pounds of vacuum at idle and one step lighter secondary spring. something's gotta be up though.
That’s good. Sucks you gotta wait til next season to try it out though. And I’m not saying start buying all this stuff, I’m simply saying I agree with converter being part of what’s holding it back. In bracket racing, converter and carb make or break a good setup. So since you got the timing figured out and it revs smooth, now you can focus attention elsewhere. With having all winter ahead of you, you can always a call a converter manufacturer and get their recommendation on what you should have for your setup being that it’s a street strip car. And at least get an idea of how close or how far off your current converter is.
