Delco 12SI, internally regulated, 94A, mid 80's Camaro and Monte.
My opinion is by the time a 'conversion' is done on a non-internal alt for more output, get a OEM 12SI.
Making a lower output, older alt produce more one needs to change the rotor, stator, etc. You create more internal heat than the design was made for, you don't get sumthin' for nuthin'....may get more output at high RPM, than the low RPM output suffers......
The 12SI 94 A is designed to output the current, handle the heat, etc. Internally reg, It drops in too.
That's my take....if you like your alt you can keep it...........
