Bare with me, I am ignorant when it comes to these motors. questions!!

[JC93Z]

I was wondering a few things.

#1 What cc are the stick heads? 48cc?

#2 Did and of the Buick motors come with aluminum heads from the factory?

#3 What compression ratio are you guys running right now, and what is stock?

#4 Do you have a picture of your oil pan from the side? I am wanting to see if it will clear my crossmember.

Thanks in advance.

I believe the stock compression is 8.5 to 1. I haven't heard of anyone trying to raise the compression on these turbo engines. I think that is a no no.

Stock heads for 86-87 are iron.

Not sure what the question is for #1.

Look at www.gnttype.org and do a search about oil pans.

Stock CR on a Buick should be 8.0 to 1
