Re: 302 Boss Motor
if only it was that simple.
a 302 boss has a lot higher compression than a standard 302. what they do is they take the crank of a 302 with connecting rods of a 289, and then they have special lower pistons to accomodate the longer stroke. it's sort of a reverse stroker, if you catch my drift. then, after that, there's still the heads like you said but i think they use 351 C heads on their boss engines. so bigger canted valves, bigger flow and so on...
hope that cleared things up for you.
