Installing A 400M Short-Block Into A 351 Cleveland Stroker Engine - Kind Of A Cleveland
400M-Stock vs Cam Research/RPM vs Cam Research/CHI
This graph illustrates the difference between the baseline run and the two intakes equipped with the custom Cleveland cam from Cam Research. As with the smaller cam, the dual-plane intake offered better low-speed power (up to 4,300 rpm) but fell off thereafter. Equipped with the dual-plane and new cam, the 400M produced 528 hp and 525 lb-ft of torque. After installation of the CHI intake, the peak power numbers jumped to 568 hp and 542 lb-ft of torque. Those are big numbers from a 9.5:1 400M boat anchor. View Related Article
