........ around and a 600 vacuum secondary carb seems about right. Larger is definiatly out and I wouldn't go mechanical secondary with that kind of gearing. I did some math and checked Holley's web page and from experience with my 289 two barrell I think this will work just fine. I don't see an reason that you will need the dual inlet center hung bowls unless it is like me, you like the looks! The carb I have available worked great, the only reason I took it off was for a slightly larger carb (on my 351C, not a 289) and appearence. Still pulled 400 on the dyno with the out of the box 1850 600 cfm carb.

As for the electric choke, I have not spent much time playing with mine but I am not overly impressed.
