The professional machine shop operators who are members of this site have warned us over and over not to trust the quality control of Eagle products. Purchase at your own risk. Measure all dimensions carefully before blindly installing Eagle products.
David Vizard, professional builder and author, tells us that the Scat cast steel crank and Scat Pro Stock rods are good for 550 hp. He has been using them for years and reports that dimensions are right on the money and that he has never fragged a Scat crank or rod. Combine Scat pieces with a good-quality forged piston such as SRP for a bulletproof reciprocating assembly up to 550 hp. Do you want to make 500 hp like everyone else? Start looking at Air Flow Research cylinder heads to use with your combination.
