I was given a small block 6 pack intake today without carbs that I'm going to put on my 340 when I finish building it. I looked on the Holley site and they have 2 that are for a 340, one is 300 cfm and the other is 500ish. They both said they were for auto transmissions. I have a 4 speed so I don't know if they'll even work, but if they will, which cfm should I be looking at?
Originally I was going to use a stock 4 bbl TQ, but since this thing fell into my lap I might as well use it, even if it is a pain to tune
