Customers appreciate the high-quality and practicality of the product, praising its perfect fit for various engine models such as the '74 Ford 302. The product is particularly useful for those not wanting to purchase a 4-bolt block, with customers recommending the stud girdle for its excellent fitment and its positive impact on performance. However, there was an issue where the threads pulled out of the nuts during torquing. Nevertheless, there are numerous repeat customers affirming they would purchase the product again due to its confirmed quality and usefulness. A point to note is the potential need for alteration of the oil pick up tube and oil pan because of the extended size with the stud girdle.
