As stated a PCV will take care of venting and you have head bolts, intake bolts, water pump bolts, and even exhaust manifold bolts to mount a fabbed generator mount to. If a 12v system the much smaller newer Delco alternator fits where a generator won't. There is no rule that says one can't drill and tap needed holes in the front of the block or even tig weld something to the intake. 8BA block with 59AB heads picture shows a drilled/tapped hole for the coil mount bracket, a small alternator, and an external point adjustment Chevy distributor. I thought hot rodders were supposed to MAKE parts to solve problems.
