Has anyone run the 2nd design off road chevy solid small block cam? I have an original LT-1 short block and was thinking about using this cam with some mildly worked over 340292 heads for a nice day 2 driver 1969 Z-28. I plan to call it "Project X" Anyway, just looking for some input on driveability, power, vacuum for the brake booster, etc.
I spent yesterday degreeing some popular cams in the LT-1, and here are the results:
note: the solids are adjusted for lash as it reduces the duration and lift specs.
1970 LT-1 Solid: Int Dur @ .006", .050" = 282, 229 deg, Exh Dur @ .006", .050" = 289, 235 deg
LCA = 114 deg, Int/Exh Lift @ 1.5 ratio = .433"/.450"
GM #3965754 2nd design Solid: Int Dur @ .006", .050" = 300, 248 deg, Exh Dur @ .006", .050" = 313, 259 deg
LCA = 112 deg, Int/Exh Lift @ 1.5 ratio = .488"/.505"
1969 Z-28 Solid: Int Dur @ .006", .050" = 304, 239 deg, Exh Dur @ .006", .050" = 304, 239 deg
LCA = 114 deg, Int/Exh Lift @ 1.5 ratio = .459"/.459" (Comp Cam Replacement)
1966 L-79 Hyd: Int Dur @ .006", .050" = 286, 222 deg, Exh Dur @ .006", .050" = 282, 222 deg
LCA = 114 deg, Int/Exh Lift @ 1.5 ratio = .447"/.447" (GM NOS Cam)
Comp 12-223-4 Solid: Int Dur @ .006", .050" = 270, 222 deg, Exh Dur @ .006", .050" = 269, 221 deg
LCA = 110 deg, Int/Exh Lift @ 1.5 ratio = .471"/.471"
For a good all around street cam, the Comp 12-223-4 would be nice, but I want something a little more nasty, that's why I was considering the 2nd design cam.
