Hi all! New to the forum scene and new to Oldsmobile. I'm a hard workin 26 yr old, bought my 84 cutlass supreme brougham 5 years ago. Drove the hell out of it for two years, put a big cam in it cause I was young and now it's been sitting for three. Now that I've got a good job I'm bout to tear into it. I want to know if I can drop a 455 into it easily. If I get an intake and headers for my 307 will they bolt on to a 455 when I find one? Lookin forward to good advice and lessons along the way. Troy

 

Welcome to classolds!

 

headers and intake will not swap to the 455. there are several guys out there with 455's in that body style so it can be done.

 

Welcome to CO! If you do a search, I'm sure you'll find some information on doing that swap.
