I've got a pro-systems 4150 and when ordered Patrick said there wasn't a difference from the cast Holley blocks he uses or his upgraded billet blocks.
After having some discussion about this with a buddy he pointed out how porus cast blocks are, how the fuel paths aren't as customizable and how casting differences can vary compared to the cnc'd billet blocks.
And most other brands use a billet block on their race carbs.
What are your thoughts, are billet blocks worth upgrading to?
