Re: 276 stroker from 35 years of parts
The EA cam is almost certainly an EAB cam. The BA cam is almost certainly an 8BA cam. The specifications for each are:
8BA intake - 0.305 gross lift; .013 / .015 lash; 0.291 net lift; 229 seat duration
8BA exhaust - 0.305 gross lift; .017 / .019 lash; 0.287 net lift; 238 seat duration
EAB intake - 0.328 gross lift; .013 / .015 lash; 0.314 net lift; 269 seat duration
EAB exhaust - 0.328 gross lift; .017 / .019 lash; 0.310 net lift; 247 seat duration
The EAB cam has a smooth idle and good mid-range.
The 8BA cam has a smooth idle and probably more low end grunt.
