TALLAMDGE, OH – September 15, 2016 – (Motor Sports Newswire) – Summit Racing has created Engine Power Bracket Blaster 572 Chevy Parts Combos. The provide performance enthusiasts the building blocks to replicate PowerNation TV’s Engine Power 756 horsepower ZZ572 big block Chevy engine.
The ZZ572 short block was torn down and freshened with Clevite bearings and a set of low-tension Mahle piston rings. The 720R aluminum cylinder heads were sent to Livernois Motorsports for some mild port work, then reassembled with Crane valve springs and retainers and a set of COMP Cams shaft mount roller rockers. The camshaft is a special-grind Crane mechanical roller with a 4-7 firing order swap to help fuel distribution and add a little power. A Jesel belt drive keeps things spinning around.
Induction, Ignition, and Headers Combo
Engine Power’s Mike Galley and Pat Topolinski tested the 572 with a Holley single-quad intake and a 1,150 cfm Holley Gen 3 Ultra Dominator (HLY-0-80905BK) and made 706 peak horsepower and 644 lbs.-ft. of peak torque. Then they got serious and swapped over a Weiand Hi-Ram tunnel ram and a pair of 750 cfm Quick Fuel Black Diamond double pumpers. That combo hit the 756 horsepower jackpot.
Watch the build and dyno testing at PowerNationTV.
