L78/L71/L72/LS6 143 "blueprint" camshaft

[Chevy454]

Everything I have references the 143 as the 68 & 69 L78/L71/L72 camshaft, and is identical to the camshaft in the 70 LS6 (362, 143, whatever). My old Crane paperwork, vintage NHRA stuff, etc, call the .520/.520 cams the 143...what # the early (1966) L72 camshaft was I have no idea. But what we reproduced was the correct .520/.520 camshaft that was used in the 1968-9 L78/L71/L72 and 1970 LS6.

Unfortunately, the camshafts are no longer available to us...but they are available through the *new* Crane, inc, via the Summit Racing website (although at a significantly higher price).
