I have had good luck with my Thumper Carb. Known Dominic for years and he has always been solid. The added expense of a custom carb will be much less than if you customize it yourself with internet knowledge. I have done several myself and it is time consuming to drill bleeds, tap the tiny holes etc.
In addition, Thumper carbs use BLP parts which are 1000x higher quality than the QF/Proform or Holley HP offerings.
