This is a guy on the board.. He's got one.. https://cleveland.craigslist.org/pts/d/1970-buick-455/6495817336.html
I called this morning was looking for a distributor guys name is John nice guy he said he sold all the stage 1 blocks carbs and distributors he said he has one set of Stage 1 heads left I would call to doublecheck to make sure he has no SS blocks left.
No luck yet with the SS block but I have a couple of fresh leads. John has the correct heads if I can find a block. Thanks again for your help! Marc
It is the same block as a 70 non stage 1 except for the SS stamp around the dip stick hole and another stamp with another car's partial VIN. I would not waste any money on it.
John's a good guy.. bought my stage 1 from him a few years ago. if he doesnt have it, he probably knows someone who does.. good luck on the hunt..
