Exactly. Why would anyone waste money on custom pistons for a 413 only to have the tiny bore size, shrouded valves and limited displacement? Rebuilding a number matching vehicle is one thing but otherwise it is just a poor choice.
Hopefully most people who read this thread will think straight and see that a 413 is the least capable of the RB motors. Just like the 350 and 361 are the worst possible B motors for a performance project.
well....there was a RB 383 for the first year or two if it's existence. IIRC it's a 4.03 bore
Ah yes, I forgot the totally pathetic 383 RB motor. Came with a cast iron carb if I remember correctly. At least the one 383 RB that I saw had an iron Carter carb on it. Evidently the reason the AFB is called an AFB! (aluminum four barrel)
