1970 Chevelle LS6 4-Speed Engine Block 3963512 CRV, COPO, YENKO, Baldwin-Motion:
VERY RARE 1970 LS6 454 450hp 4-Speed Block 3963512 cast date K-7-9 code T0227CRV. This block has been stored away for over 20 years and has now been machined ready for service. Block has one sleeve installed due to a very small void on the cylinder wall and all 8 cylinders are rough bored to .025 ready to be honed for a .030 piston of your choice. It has been completely cleaned, magnafluxed, pressure tested, and mainline is all done. This block is verified and is the real deal GM performance service replacement block with no vin #. Another cool thing about this block which I have never seen before is the HIPER ASS instead of the HIPER PASS in the front casting. Be aware of other listings claiming to be standard bore blocks, as with all big blocks they are rarely straight from the factory and will require cylinder boring and line boring work. I was not comfortable selling this block until I was sure of it's condition and having a good bill of health. You will also find other listings not having or willing to have the machine work done before the sale and are asking a fortune for it. I also have a set of NOS 7/16 rods, the date matching set 3964291 or better known as 291 heads that are all done and ready to install as well as the intake that are not included in this sale but I will sell separately if there is any interest. You are welcome topick up yourself. Please ask questions and know what you are offerding on. Shipping will need to be determined at the end ofthe sale. Based on other listings shipping shouldn't be more than$350 depending where you are for the lower 48 states all other areaswill require additional cost. All sales are final, no returns and payment is due at end of sale.
