I looked at a engine that is for sale and the block code is 25514290 . What year and what size is this engine? Is this a turbo engine. Thank you for your time, Bruce.

According too www.butlers-a1.com/buickm.htm
that casting number is for a 3.8 turbo 79-84. I hope that helps. I have the 78-87 GN facts and figures book too but I havent read it so Im not sure if there is casting numbers on the block in there. Hope this helps.

I have an original 25514290 in my '83 TR. :) 25514290 is a 3.8, but it may have been used in NA applications as well. If it has any thing bolted to it, like an intake, it should be pretty clear if it was a turbo or 2-barrel.
 
Thanks guys for the quick responce. I'll buy the engine today before someone beats me to it. Rich I'll see you at byron on the 27th :)
Going Fast With Class Bruce.
