Best E58 360HP Camshaft....your guesses

He wrote differant specs for the lift for 70-71 and list 2 cams for these yrs.

1970-71 engines were painted orange; they changed to blue very late in the 1971 model year; the camshaft on automatics had a 268° intake and 276° exhaust opening duration, with 44° overlap (manuals had 276° intake, 284° exhaust, 52° overlap). Valve lift was 0.430" intake, and 0.445" exhaust.

Well, like I said, I've never in my life seen or heard of the 68 4 speed cam being used in any other year. Course, I ain't seed it all by a country mile either, but that coincides with everything I've ever read everywhere including on this forum. Certainly, it's entirely possible they used that more aggressive 4 speed cam later than 68. This will be the first I've ever seen or heard anything about it......but like I also said, that don't mean "much".
