The 270S Comp Cams I quoted earlier is a solid lifter cam. Because my understanding is this engine used a sol lifter cam....
Somebody else recommended the XE 256 cam. That is a hyd cam, 212/218 @ 050.
According to Crane Cams, to get a rough comparison of a sol to a hyd cam, you need to ADD 8-15* to the 050 duration. 8* if it is tight lash, 15* if it is wide lash.
The 270S has variable lash. If you lashed it at 0.030" lash, the duration is reduced 10*, now a 260 degree cam & a reduction in the 050 number as well. Power range listed as 1500-5500 rpm. So I do not see how it could be too big, considering what the OP is seeking.
