Ask any questions you like. That's how we all learn. There are never stupid questions, only stupid people. Lol! Some people on here make comments about the repetition of questions. Sometimes we forget that people come and go off of this site all of the time. What people need answers to aren't in the first couple of pages listed and we all know too well how wonderful the SEARCH function works on here.
My old combo with a 262/266 lift on my 440 liked a 6,800 rpm shift point. Car would slow down with a 6,500 or 7,000 shift. You'll find the sweet spot real quick.
