1970 buick 455 for sale. Complete from carb to pan eccept timing chain cover and water pump. I can't think of the casting #'s off hand but if any one needs it I can get it. I do know the engine code is SF, out of a Riviera, 370 hp and 510 tk. It ran when it was pulled but it was'nt mine so I cant say for sure how it ran. If your looking to rebuild a 455 then this is your block. I'm located in nassau county long island New York. Motor must be picked up, no shipping. Make an offer. Thank you- Vinny
