Engine Swap (?)

Unread post by BryanDee » Sun Feb 18, 2018 8:17 pm

Hey there, New to the site and have a question before I screw up and get a "told ya" remark. I have an 04 Alero with the 3400 motor and a 99 Grand Prix with the 3400 motor. The 99 Grand Prix has a cracked head I'm sure since it was run hot after a wreck and has the telltail sign of milky colored oil on the dipstick. Question is will the 3400 from the Alero fit without any mod into the 99 Pont or will it be a bad idea?

I don't show a 3.4 for 99 Grand Prix. I show that it has 3.8's and 3.1.

you might want to check with a wrecking yard about the engine and year interchanges but from what I have read it is not just a simple engine swap though the engine look similar.

Will the heads swap out instead of trying to do a complete engine swap?
