3.8L parts on a 3.3L

No53Alero · Posted: Fri May 07, 2004 6:58 pm

i was wondering if I could find a set of headersfor a 3,8l to put on my 3.3L The engines and exhaust are extremely similar. I found some for a Buick Century 3.8L on jcwhitney's site but the year isn't listed. I had my friend look up exhaust manifold gaskets for my car and a 3.8l century and they use exactly the same part! also If I could find a bigger throttle body for a 3.8L I was wondering if it would fit, I know some earlier 3.8's look awfully interchangeable. my manual says the 2 engines only have a .10" bore difference. Would it be beneficial to swap if the parts are similar and fit?

Welcome to TOC.

It's an old post and the subject has been done to death.

Short answer is: Not practical
