1969-70 3963512 4-bolt
 

While searching for a good 427 block, I came across this little gem. Casting date is November 11th, 1969. It was still standard bore but had light surface rust developing so I had it rough bored for a + .030" piston. Will need final honing for your slugs. I also had it square decked.
There are no sleeves, helicoils, cracks, repairs and none needed. I am located in Mishawaka, Indiana 46545. I can ship if needed. I believe a fair price for this block and the machine work is $3,200 picked up.
