i bought a 350 at the junk yard it's valve covers are center bolt i know its 5.7 any one know

 

If it has center bolt valve covers, it is not an Oldsmobile engine, it is a Chevrolet.

 

all monte carlos come with the 305??? or 350??

 

Depends on the year. The 305 came out in '76 or '77 - I can't remember which. Prior to that, the 350 was the smallest (and most common) Monte engine. At some point in the late 70s or very early 80s, the 305 was the BIGGEST Monte engine you could get. Chevytalk.org is a great website for the bowtie guys.
