402 Chevy Ls2 Short Block Engine Build Zex Perimeter Plate
|
In typical CHP fashion we left no options unturned in search of additional horsepower. We used a Holley 950-cfm HP for our baseline pulls and made 589 hp and 534 lb-ft. As testing progressed, we stepped up the cfm and fuel demands by using a Holley 1,000-cfm HP and added a 1-inch Wilson spacer, which then bumped power to 608 hp and 542 lb-ft. However, for all the beans, we topped it off with a Zex perimeter plate. Being conservative, we tested the waters with a 150 shot and produced 744 hp and 763 lb-ft. We didn't stop there. Stepping up to a 200 shot rang the bell with 780 hp and 801 lb-ft! View Related Article
