Slow 1/8 with 74 440 dart

lolz love your advice. yes throttle is opening all the way although i did have that issue at one point. i have yet to get good at reading plugs but they don't look terrible. 150psi on all cylinders. and i don't dare let my buds work on it as they're all into hondas and imports. but i'm only 19 so it's hard to find younger people with old cars ha
Spark plugs can read rich/lean. But the strap will also tell you where your initial and total timing is and if it needs more or less or one or the other.
Love to hear your 19 and working on a Big Block A-body. I wish you were closer, I'd love to help you ..
