Except a 63 or 64 Corvette 300 hp code would be RD.What I'm going to say will probably ruin my reputation but................( go ahead guys...I can handle it!!!!!!!!!!!!!!!!!!!!)...........I have a complete 63 RB shortblock assy, has oil pan and water pump. Casting date is B163 and the assembly date is FO214RB. Happy Valentine's Day!!!!!!!!!!!!!!! It is the 870 casting number. The Flint block makes it correct for any 63 Corvette.
I can post pictures of you like. Yes, it's for sale. I don't have any double-hump heads and 64 300HP exhaust manifolds are one year only.
Yes Mr. Cecil.............but I believe my statement is still correct and "right". Blocks were cast in Tonawanda and Flint plants. Passenger cars used blocks from both foundries but Corvettes used only Flint blocks. You could deck this block and "wa-la"...........you too can have a matching numbered block now!!!!
Very nice car! Great car, congratulations. Franz
Leo, I don't know where this build sheet originated from, but when I was helping the former owner try and sell the car, it was in a folder with a lot of maintenance records and whatnot. I have heard of them being found on top of the gas tank, and even behind the backseat between the springs and foam. I'll see if I can locate the original and scan it. I'm sure I'm not the only one on here to have seen one of these rare gems!
