Customers found the product highly compatible and integral for tri-power projects, especially in maximizing the performance of Rochester 2g carbs. The product's fit and finish are praised, despite some trial iterations for perfect fitting. However, there's an isolated issue of the throttle plate not fitting right. The provision of hard-to-find parts sets the product apart from others.

Correctly convert Rochester 2g to an end carb on sbc tri power. Nice finish and fit Took some trial and re-trial to get the fit exactly right.
