5 of 5 WOW January 17, 2023
Reviewer: William Demaray from Albuquerque, NM United States  
Wow best describes my experience. After getting 4-8 months lead time from many engine suppliers, including GM Performance. Then finding ATK with the perfect long block configured exactly as needed at a great price.
I ordered on Wednesday morning and that afternoon the carrier called me to arrange Friday delivery. 2 days opposed to 4-8 months - WOW!
