ive been told its more then likely is a 109 block its a turbo 3.8 in 81 it was just called a regal turbo and it was a carb job though i just trying to make sure it would work for sure before i go to get it ill have to see if i can get some numbers off it.
Looking to build a new engine for my 87 gn found a block out of a 81 buick regal turbo woundering if this block is the same as the 87 want to build and still be able to drive my car?
