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.
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.
