So I pulled this 350 out of an old suburban I had, it smoked, but otherwise ran good. I had no idea about the motor, just thought I'd throw a set of new rings in it and then run it in the Blazer. I got around to pulling it apart today and low and behold, I got a 4 bolt main 350 !
Now I can save that 521 caddy I got for a future project.
