Both standard belongs to a friend, don't know if it is CJ stuff or not at the moment, and he says it will most likely need to be bored to 10 over. Range of value numbers on it would be good. Thanks,
Rich

Does it matter which crank and block?

I would think CJ would be worth more than just a standard block and crank.

There's a lot of gray area with early pieces . . .

Cranks are exactly the same, CJ or not. As to the block, for a CJ restorer a date code and proper "C" on the back will make a difference. But there are blocks that are exactly the same as the early CJ blocks that may not have all the same markings. And just being able to prove it is a true 428 block makes it valuable. You can't do it with a casting number only.

Several things make up the value

October 10 2017, 6:41 PM 

Early two rib A scratch block are worth on the low side say 800 to 1000. Maybe a touch more if you get into 67 Shelby dates that goes up from there , say 1200.00 to 1500.00. Cranks 1u and 1ub will be 300 to 400 . 1ua goes up from there. It also requires a cookie cutter and a special balancer, which are expensive also. C scratch blocks with 3 ribs will bring them most as the cars are worth the most.The early 68.5 stuff will bring the best money. Mid 69 stuff is the most common. 70 stuff is harder to find and a little more money than 69. Jim has it about right for a good CJ block. Now having all that said to get the high end it need stop be cleaned and magged from a shop showing that it is good. No sleeves or no damage. Any damage it goes down from there. Also most blocks that have been ran much will need bored more than .010 over. That is only .005 on each side. If you can get by with .020 would be a real nice block. Hope that helps

Many thanks to all of you.

I will try and get more information on the block and crank numbers etc. I will most likely not be interested in the block and crank, but you never know. If not interested, I will list what it is and what he wants. Good friend and just trying to help him establish a price. Will also try and get pics.
Thanks to all,
Rich
