Up for sale I have a 1968 & 69 Chevy Big Block #3955272 . Its an Original 396 bored out 30 over to make it a 402, cam is line bored 10 over for 325 & 350 Horse Power. As you can see it is a 2 Bolt Main. Date coded J 11 8 which is October 11th 1968. I started building it my self, sent it out for the boring and brought it home put new frost plug in it and put it all together and found out there is a hole in the passage way for the fuel pump rod. It will need to be welded or a sleeve installed. I haven't got that kind of talent so I bought another block. This one is going cheap. They are selling for up to $2500 on eBay. Your luck is my lose. http://ontario.kijiji.ca/c-cars-vehicles-classic-cars-1968-1969-ENGINE-BLOCK-3955272-396-CU-IN-325-350-Horse-Power-W0QQAdIdZ282451439
