Great point about the od trans! What rpm do you get out of the 402 and is it stock or modified? Carb sizing is one thing I'm not clear on. I always heard to go with 750 no matter what growing up, but over the years have learned that's complete non-sense. I know there is a bit that goes into, but not sure what. I run 600cfm carbs on 355's with great results, but would think a 625 is too small for much anything over this. On the other hand, I see 500cfm 2 barrels on race cars all the time and they run great.

What all would you take into consideration when choosing a carb?
