Hot Rod - - Ls3 Intake Shootout! -

We had very good suc­cess with the Pro-Flow in our test on the cathe­dral-port in­takes, and this rec­port (LS3) ver­sion con­tin­ued the trend. The Edel­brock Pro-Flo XT showed its high-rpm strength by mak­ing peak power at 7,000 rpm, even on the big-inch LS3 stroker. Rac­ers have run these in­takes with great suc­cess on high-rpm, turbo ap­pli­ca­tions. Equipped with the Pro-Flo XT, the 415 stroker pro­duced 656 hp and 551 lb-ft of torque, which rep­re­sented a gain of nearly 30 hp over the stock in­take. The peak torque out­put was down 17 lb-ft, but torque suf­fered through much of the rev range, some­thing we have come to ex­pect with short-run­ner in­takes (at least com­pared to the stock in­take).
