noch ne Info - vielleicht wenn schon Reaper, besser die 525er, bei der 574er werden Performanceparts für den Ventiltrieb seitens Hersteller empfohlen ...
525 Cams - A real workhorse, designed to increase torque band width and increase fuel economy. Great bolt in camshaft upgrade for stock 88 & 96" engines also performs very well in 103" strokers. Produces strong low and mid range power with a linear horsepower and torque curve. Can be used with factory valve springs, pushrods and lifters. Increases throttle response and eases starting. Will also respond well to increased compression and cylinder head work. RPM 1,750 - 5,500
574 Cams - Wicked power band for modified engines and an excellent bolt in for stock 96, 103 & 110 engines. This is a great all around camshaft with solid low end performance and mind blowing mid and top end power. Extremely smooth cam lobe design creates a very smooth valve-train motion. Responds very well to modified cylinder heads, increased compression ratio, performance exhaust and intake systems. Performance valve springs are required on 99-04 engines and performance pushrods, lifters and clutch modifications are recommended. RPM 2,100 - 6,500
