I have e-mailed comp about the specs for their 240H and 252H cams at .100 and .200 lift. I then went to Crane with the same idea but instead found specs at .200 lift for all lobes used in all three cams they make for a 250. They are: 200511 intake at .050 192deg at .200 83deg. Exhaust 204deg at.050 114deg at .200 lift. 203901 204deg at .050 114@ .200. This is the same lobe used as the exhaust on the first cam. For 203901 exhaust its 216 @.050 and 127@ .200. Compare as this to the stock 292 cam the Crane200511 has about 5deg more duration @.200 lift. I also found from looking at the lobe charts the more radical the cam the bigger the difference in duration at .200 lift. Is 5deg at .200 a lot? I don't think so at the level of cam that I am looking at. IMHO the Clevite 229-1878 would fall somewhere in the middle between the stock and Crane cams at .200 lift. I will report back what I hear from Comp Cams. Thoughts anyone? Jay
