which is it?

OK, I have been trying to sell this big block Ford engine for some time. I am positive it's a 429, but the guy who just came to look at it says it's a 460 and declined to purchase. Here are the numbers.

Heads C8VE-E
Block C9VE-B
Rods C8VE-A

I have researched and discovered that there will be a 4U or a 4UA on the crank if it is a 429. It does have the 4U stamping. However, I only discovered all this after he left. Is there any other way to be 100% certain it is a 429? I also read the blocks are identical right down to the bore, but the pistons are different from a 429 to a 460. If this is the case, what would I look for on a piston? I have not pulled one out yet.

The 429's and 460's, on any given year of production, are identical in ALL parts except for the crankshaft (stroke) and the pistons (pin location). Therefore, if you have a 4U crankshaft, then your engine is absolutely, positively, 100% certainly a 429.
