Feuling's Reaper 574 Cams have a 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 are recommended. RPM 2,100 - 6,500
