That cam is the old -178 solid lifter cam, not to 30-30 or the 2nd design -140 solid cam.

Look through this and it is the last cam...

Being that PDQ did all the foot work , my guess if the guy told you it was the 70 Lt1 cam, I would say it is the 3972178 cam. Pull it to be sure. Casting # will be between lobes.
