Morning.
Those 3800 engines are great but have weak points. I had one in a Grand Prix that I bought after getting laid off the first time. It ran great but had seepage around the intake. My BIL and I were going to replace them but I sold the car before we got to it to get my Protégé 5.
AFAIK, it is still running. We sold it to a former coworker of my wife.
I think you are making the right decision with the Buick. Just be careful with your back when doing it.
Hmmmmmm, they do make a supercharged version of it. Granny hot rod maybe?
