As everyone else above has said, there are many arguments for whether this combo is better or not.
The 302C rod is longer in length than a 351C, and so as above a shorter height piston has to be used.
Some believe the better rod angle provides better bore/piston wearing, and the longer tdc time allows for better burning, as well as many other pros and cons, including a better/stronger feel through the mid-range rpm.
I personally have a stance of neither for or against.
I have built many 351 rodded 351 Clevo's and one 302 rodded 351 Clevo.
I must say (although it could be a couple of things) that in the 302 rodded engine it does feel much smoother and stronger during the midrange rpm and slightly better in top end.
I am comparing this against an engine that had same cam, same exhaust, similar exhaust setup, same g'box, diff ratio, similar carby, same ignition.
As I say, it may be put down to differences else where in the engine, but it does definatly feel stronger.
