Episode 55 - High Performance Only Engines

Today I talk about High Performance Only Engines, that is Muscle car engines that didn't have a low performance version, or the low performance version was enough different that the basic engine block wasn't the same. Like the Chevy 302 in the first gen Z/28 or the Mopar 340, there was no low performance version. Others, there were changes in the basic engine block, like going to 4 bolt mains for more strength: Or even cross bolted mains: Some Like the previously mentioned 302 and 340, like the Ford 427, didn't come in a low performance version. Some Like the ZL1 427 used aluminum for the engine block to save weight.
