Just get it running the way it is first then throw a 2bbl on it later after you gather all your parts. I doubt you notice much difference without other mods. I spent time and money on a leaning tower once and was unimpressed with the performance. I’m glad I did it and had a lot of fun but If I do it again it will be with a turbo. I used a bbd and it ran great, As far as single barrel carbs go I liked the bbs better than the Holley. I always wanted to try a dual bbs setup
