340 Chugging instead of Reving

Just a brief update so ya know I didn't abandon the forum. I should be back in my shop over the weekend to begin the series of changes and I'll update until this is car is running like it should. One misperception in my original post, is that I have been chasing this problem for a couple weeks. In my garage 2 weeks equals about 7 hours lol. I get small windows of time in-between other obligations. I built this drag car completely over a 3 year period which could have taken 3 months in some of your shops I'm sure. But this my retirement hobbie and I appreciate all the advice that's been offered.
